Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and in particular to a wireless communication device for a substation. Background Art

[0002] The substation communication base station is a communication facility set up in the substation environment. It is mainly used to realize the communication between various devices in the substation, as well as the information exchange between the substation and external power grid dispatching center, remote monitoring center and other institutions. There are a large number of power equipment in the substation, such as transformers, circuit breakers, disconnectors, etc. The communication base station can collect the operating parameters of these devices in real time, such as voltage, current, temperature, switch status, etc. For example, through the sensor installed on the transformer, the oil temperature data is transmitted to the communication base station, and then sent to the monitoring center, so that the operation and maintenance personnel can understand the health status of the equipment in time. The operation and maintenance personnel need to inspect the communication base station regularly. Check the operating status of the communication equipment, including whether the indicator light of the equipment is normal, whether the interface is loose, etc.; when the communication base station fails, it needs to be repaired in time.

[0003] Hidden communication base stations are commonly used in communication base station designs, which make their appearance or installation method difficult to be easily detected. The purpose is to better integrate into the surrounding environment while meeting the communication coverage requirements, avoid bird activities interfering with communication equipment, and reduce the impact on the surrounding landscape and the psychology of the public. For example, the base station antenna can be disguised as a chimney of a building. It can also be disguised as a decorative component of a building, such as designing the base station antenna to resemble a part of an architectural sculpture on the facade of a European-style building. The base station can also be disguised as a tree.

[0004] It is more common to set a fiberglass decorative pole around the base station communication antenna to hide the communication antenna without affecting signal transmission; such as the patent with publication number CN219933937U, a lamp pole with a hidden communication base station; the patent with publication number 215717670U, a new type of quick-install urban communication tower.

[0005] The advantages of hidden communication base stations are: good landscape coordination. For tourist attractions, historical and cultural cities and other areas with high landscape requirements, hidden communication base stations can avoid the abrupt visual experience of traditional base station towers. Reduce public resistance. Due to its hidden characteristics, hidden base stations can reduce public resistance to base station construction, allowing communication network coverage to be carried out more smoothly.

[0006] The decorative pole-style hidden structure forms a smaller vertical gap, which neither affects the heat dissipation of internal equipment nor prevents birds from entering to build nests, causing communication antenna cables to loosen and signals to be interrupted.

[0007] The disadvantage of the decorative pole hidden communication base station is that the communication antenna is inconvenient to install and maintain. While hiding the communication antenna, it also blocks the communication antenna. The patent with publication number CN113931426A discloses an antenna bracket maintenance platform based on a shared pole tower and its use method, which can provide support for installation and maintenance personnel. The maintenance platform can be folded, which can not only provide a larger support area for personnel during maintenance, but also prevent birds from moving on the maintenance platform after folding; but it cannot protect and block the communication antenna and prevent the communication antenna from being disturbed by bird activities; and the support surface of the maintenance platform is made of flexible Oxford cloth over a large area, which has poor support stability for personnel; it only provides lower side support, and the lack of protection on the outer ring side leads to low safety.

[0042] Specific embodiments of the substation wireless communication device provided by the present invention: See also Figure 1-17 The wireless communication device of the substation includes a tower body 1; the tower body 1 is a hollow rod-shaped structure, and the tower body 1 of the wireless communication device is a lightning tower of the substation.

[0043] A vertical communication antenna 2 and a number of decorative poles 5 surrounding and shielding the communication antenna 2 are installed on the outer side of the upper part of the tower body 1; an insulating sleeve is provided on the outer side of the upper part of the tower body 1, and a horizontal support pole and a vertical holding pole are connected to the outside of the insulating sleeve. The holding pole is connected to the outer end of the support pole, the holding pole is vertically arranged, and the communication antenna 2 is installed on the outer side of the holding pole.

[0044] The decorative rod 5 is vertically arranged and evenly distributed around the circumference; the communication antenna 2 is located on the inner side of the upper part of the decorative rod 5 .

[0045] Two layers of support seats are provided on the outside of the tower body 1 corresponding to the upper and lower ends of the decorative rod 5 respectively; an insulating ring is provided at the connection between the support seat and the tower body 1; the support seat includes two layers of annular plates 3 surrounding the tower body 1, and there is a gap between the two layers of annular plates 3, and the communication antenna 2 vertically corresponds to the inner side of the edge of the annular plate 3 and does not exceed the vertical range of the annular plate 3.

[0046] An arc rod 4 is rotatably connected between the inner edges of the two layers of annular plates 3, which corresponds to the decorative rod 5 and supports the end of the decorative rod 5. Pin holes 301 are evenly distributed on the circumference of the inner edge of the annular plate 3. A pin column 401 is provided at the inner end of the arc rod 4. The pin column 401 and both ends extend into the pin holes 301 of the two layers of annular plates 3 respectively, so as to realize the rotation support of the arc rod 4.

[0047] Because the support base has two layers, the arc rod 4 also has two layers. The arc rod 4 has a first state hidden between the two layers of annular plates 3 of the support base and a second state partially extending from the support base; the arc rod 4 can be switched between the first state and the second state by rotating the arc rod 4; when in the first state, the decorative rod 5 is in a vertical state and the upper and lower ends are attached to the outer sides of the upper and lower support bases. The decorative rod 5 and the two layers of support bases form a cylindrical space surrounding the tower body 1 and the communication antenna 2. The internal space formed by the decorative rod 5 is small, and the adjacent spacing of the decorative rods 5 is small, which can prevent birds from entering, playing the role of hiding and protecting the communication antenna 2, and then the communication antenna 2 will not malfunction due to bird activities, reducing the occurrence of malfunctions. When in the second state, the internal space formed by the decorative rod 5 is large, and the adjacent spacing of the decorative rod 5 is large. There is space for staff to stand between the decorative rod 5 and the support base, and between the decorative rod 5 and the communication antenna 2. The lower arc rod 4 provides support for the staff, and the outer decorative rod 5 provides safety protection for the staff, which is convenient for the staff to install or repair, and provides sufficient safety.

[0048] like Figure 5 As shown, the arc rods 4 are densely and evenly spread out, which can provide stable foot support for the staff and completely prevent the staff from falling. Flexible sun umbrella cloth can be connected between the upper arc rods 4 and the adjacent arc rods 4 to achieve the effect of sunshade and rainproof.

[0049] In order to further improve the stability of the lower arc rod 4, a bottom ring 7 is provided on the outer side of the upper part of the tower body 1, which can rotate horizontally and move vertically along the tower body 1. The bottom ring 7 is located below the decorative rod 5. A reinforcement rod 6 is hinged between the bottom ring 7 and the bottom of the decorative rod 5. The reinforcement rod 6 is vertically identical to the decorative rod 5 and corresponds one to one. The reinforcement rod 6 reinforces the stability of the outer end of the lower arc rod 4 and the lower end of the decorative rod 5 to provide sufficient lower support.

[0050] A guide column 8 is connected to the inner side of the bottom ring 7, and a spiral hole 9 cooperating with the guide column 8 is provided on the side wall of the tower body 1; because the bottom ring 7 rotates around the tower body 1 and the arc rod 4 rotates around its own inner end, the rotation centers of the two are different, and the angle range corresponding to the spiral hole 9 should be larger than the angle of rotation of the arc rod 4 from the first state to the second state, so that the bottom ring 7 can adapt to the rotation of the arc rod 4; and because of the different rotation centers, the lower end of the decorative rod 5 itself will have an angular deflection relative to the center of the tower body 1, so the reinforcement rod 6 and the bottom ring 7 are hinged by a ball joint, and the ball joint bonding has more degrees of freedom, which can adapt to the angular deflection of the lower end of the decorative rod 5 relative to the center of the tower body 1.

[0051] When the bottom ring 7 is raised or lowered, the angle of each reinforcement rod 6 changes, so that the lower arc rod 4 can rotate and switch between the first state and the second state, so as to realize the unfolding and folding of the decorative rod 5; and the upper arc rod 4 can be synchronously switched between the first state and the second state. All the arc rods 4 and the decorative rod 5 rotate together.

[0052] In order to ensure strength, the annular plate 3, the arc rod 4 and the reinforcing rod 6 are all made of metal, preferably steel or aluminum; the decorative rod 5 includes a fiberglass section, which has high strength, durability and corrosion resistance and will not shield the signal of the communication antenna 2; in order to ensure the connection strength between the decorative rod 5 and the arc rod 4, the upper and lower ends of the fiberglass section are provided with metal sections 501, and the metal section 501 is made of steel and aluminum; the combination of metal and fiberglass materials not only ensures the strength and stability of the rotation support, but also avoids the shielding of communication signals.

[0053] In order to facilitate the staff to enter and exit the decorative rod 5, the lower end of the decorative rod 5 is detachably connected to the outer end of the lower arc rod 4; the upper end of the decorative rod 5 is hinged to the upper arc rod 4.

[0054] Specifically, the outer end of the upper arc rod 4 is connected to an upper hinge seat 10, and a first torsion spring 11 is provided at the hinge between the decorative rod 5 and the upper arc rod 4. The first torsion spring 11 is located between the upper hinge seat 10 and the upper metal segment 501 of the decorative rod 5. The first torsion spring 11 causes the lower end of the decorative rod 5 to rotate away from the tower body 1; in this way, after the lower end of the decorative rod 5 is disassembled and separated, the lower end of the decorative rod 5 can be automatically opened to facilitate the entry of staff.

[0055] The outer end of the upper arc rod 4 has a first stopper 12 for limiting the rotation angle of the decorative rod 5; the first stopper 12 is horizontally U-shaped and limits the rotation angle of the decorative rod 5 under the action of the first torsion spring 11, so as to prevent the lower end of the decorative rod 5 from being excessively opened, and to facilitate closing; so that the staff standing on the unfolded lower arc rod 4 can hold the decorative rod 5 to the upper part. The first stopper 12 limits the rotation angle of the decorative rod 5 to between 20 and 30 degrees, and in this embodiment, it is 23 degrees.

[0056] The metal section 501 at the lower end of the decorative rod 5 is provided with a movable column 14 that slides linearly along the extension direction of the decorative rod 5 and a coil spring 19 that makes the movable column 14 close to the upper end of the decorative rod 5; the lower end of the decorative rod 5 is provided with a slide groove, and the middle part of the movable column 14 is provided with a slider that slides along the slide groove; specifically, the metal section 501 at the lower end of the decorative rod 5 is provided with a through groove 502, the movable column 14 passes through the through groove 502, and both ends extend to the outside of the through groove 502, the through groove 502 is provided with the above-mentioned square slide groove, the slider is a square block matching the slide groove, and the width of the slide groove is greater than the width of the through groove 502. The coil spring 19 is located in the through groove 502, and two are provided, symmetrically on both sides of the slide groove, the coil spring 19 is connected to the side of the slider facing the lower end of the decorative rod 5, and the other end of the coil spring 19 is connected to the inner wall of the through groove 502.

[0057] The outer ends of the lower arc-shaped rods 4 are connected to the sockets 13, and the sockets 13 are provided with slots 1301 that cooperate with the movable column 14. The slots 1301 include a vertical portion and an inclined portion whose lower end is connected to the lower end of the vertical portion, and the inclined portion extends from the end away from the vertical portion to the edge of the socket 13; when the lower end of the decorative rod 5 is separated from the socket 13, when the upper part of the decorative rod 5 is held, the lower end of the decorative rod 5 approaches the socket 13, and the movable column 14 first enters the inclined portion of the slot 1301, and the decorative rod 5 continues to be rotated. The inclined portion causes the movable column 14 to compress the coil spring 19. When the movable column 14 enters the vertical portion, the coil spring 19 releases the elastic force to cause the movable column 14 to enter the upper end of the vertical portion. At this time, the movable column 14 restricts the rotation of the decorative rod 5, and the lower end of the decorative rod 5 is connected to the socket 13 at the outer end of the lower arc-shaped rod 4.

[0058] The holder 13 is hinged to the reinforcing rod 6. Specifically, the lower end of the holder 13 is connected to a lower hinge seat 1302, and is connected to the reinforcing rod 6 through the lower hinge seat 1302. The upper hinge seat 10, the holder 13 and the lower hinge seat 1302 are all made of metal.

[0059] In this embodiment, there are two ways to separate the lower end of the decorative rod 5 from the seat 13; the first is to facilitate the staff to open it from the lower side of the outer side of the decorative rod 5, so that the staff can enter the decorative rod 5; the second is to facilitate the staff to open it from the inside of the decorative rod 5 after completing the installation or maintenance work, so that the staff can come out of the decorative rod 5.

[0060] The structure corresponding to the first opening method is as follows: the lower middle part of the movable column 14 is connected to a traction body 20, the lower end of which passes through the side wall of the through slot 502 at the lower end of the decorative rod 5 and extends below the lower support seat. The traction body 20 includes a flexible rope body, the lower end of which is connected to a pull ring. When the lower end of the decorative rod 5 is connected to the clamping seat 13, the staff climbs to the bottom ring 7 and pulls the pull ring to compress the spiral spring 19 of the movable column 14. When the movable column 14 moves downward from the vertical part of the clamping slot 1301 to the corresponding inclined part, the first torsion spring 11 causes the lower end of the decorative rod 5 to pop out from the clamping slot 1301.

[0061] The second opening method corresponds to the structure: the movable column 14 is connected to the side of the tower body 1 with the diagonal support frame 15, and the upper end of the diagonal support frame 15 is connected to the foot pedal 16. After completing the installation or maintenance work, the staff steps on the foot pedal 16 to move the foot pedal 16 and the diagonal support frame 15 downward, and then drives the movable column 14 to move downward along the vertical part of the slot 1301 to the corresponding inclined part of the slot 1301, and the first torsion spring 11 causes the lower end of the decorative rod 5 to pop out from the slot 1301.

[0062] like Figure 3 and Figure 4As shown, the lower ends of all the decorative rods 5 are separated from the holder 13, i.e., the decorative rods 5 are all opened. In actual operation, it is not necessary to open all the decorative rods 5, but only a number of adjacent decorative rods 5 need to be opened for the staff to pass through.

[0063] The upper side of the footrest 16 is provided with anti-skid patterns. In order to prevent the footrest 16 from occupying a large space, the footrest 16 is hinged to the upper end of the diagonal support frame 15, and a second torsion spring 17 is provided at the hinge. The second torsion spring 17 makes the end of the footrest 16 rotate toward the decorative rod 5. The diagonal support frame 15 is provided with a limiting protrusion 1501 for limiting the rotation of the footrest 16 toward the decorative rod 5. When the limiting protrusion 1501 limits the footrest 16, the footrest 16 is in a vertical state, which can save space. There is a spacing between the footrest 16 and the decorative rod 5, which is convenient for using the foot to make the footrest 16 overcome the elastic force of the second torsion spring 17 and rotate to a horizontal state; the end of the diagonal support frame 15 is also provided with a second stopper 18 for limiting the rotation of the footrest 16 toward one side of the tower body 1, so that the footrest 16 can rotate within a certain angle range. In this embodiment, when the second stopper 18 limits the footrest 16, the footrest 16 is in a horizontal state; in some other embodiments, the second stopper 18 can limit the footrest 16 to an inclined state.

[0064] After the installation or maintenance work is completed and the decorative rod 5 needs to be opened, the foot drives the foot pedal 16 to rotate first. The foot pedal 16 overcomes the elastic force of the second torsion spring 17 and rotates to the state where the second stop block 18 is limited. The anti-slip groove side of the foot pedal 16 faces upward. Press the foot pedal 16 downward with force to move the foot pedal 16 and the diagonal support frame 15 downward, so that the movable column 14 can be disengaged from the slot 1301 of the base 13.

[0065] The tower body 1 is provided with a lifting frame 21 for driving the guide column 8 to rise and fall. The lifting frame 21 includes two layers of plates and two columns 2101. The columns 2101 are connected between the two layers of plates. The two columns 2101 are arranged symmetrically. The lifting frame 21 moves vertically without rotating, and the two columns 2101 do not affect the rotation of one guide column 8 within one hundred and seventy degrees. The guide column 8 extends between the two layers of plates. In this way, the lifting frame 21 can drive the bottom ring 7 to move vertically through the guide column 8 without affecting the rotation of the bottom ring 7. When the bottom ring 7 moves vertically, the spiral hole 9 rotates the bottom ring 7 through the guide column 8. The upper side of the lifting frame 21 is connected to a driving structure for driving the lifting frame 21 to rise and fall. The manual driving input end of the driving structure is located at the tower body 1 on the inner side of the lower part of the decorative rod 5.

[0066] The upper side of the upper plate of the lifting frame 21 is connected with the first lifting column 22. The tower body 1 on the upper side of the lifting frame 21 is provided with a first guide ring 23. The first guide ring 23 is provided with a through hole for the first lifting column 22 to slide through. The through hole is eccentrically arranged. A rack is provided on one side of the upper part of the first lifting column 22. A gear 24 and a worm wheel 25 are rotatably installed in the tower body 1 on the inner side of the lower part of the decorative rod 5. The gear 24 meshes with the rack on the upper part of the first lifting column 22. The gear 24 and the worm wheel 25 are coaxial. A worm 26 meshing with the worm wheel 25 is also rotatably installed in the tower body 1.

The lightning cone 30 can be connected to the tower body 1 through a soft cable, which does not affect the lifting and conduction of the lightning cone 30.

[0069] The lower side of the lightning cone 30 is connected to the second lifting column 28, and the inner side of the upper part of the tower body 1 is provided with a second guide ring 29. The second guide ring 29 is provided with a through hole for the second lifting column 28 to slide through, and the through hole is also an eccentric hole; a rack is provided on one side of the lower part of the second lifting column 28, and the rack is meshed with the gear 24. The rack of the first lifting column 22 and the rack of the second lifting column 28 are meshed on both sides of the gear 24. In this way, when the first lifting column 22 and the lifting frame 21 rise, and the arc rod 4 and the decorative rod 5 are unfolded, the second lifting column 28 and the lightning cone 30 are lowered until the lightning cone 30 is hidden in the tower body 1, and no longer provides a tip effect, avoiding lightning strikes. Improve the safety of maintenance work. When the first lifting column 22 and the lifting frame 21 rise, and the arc rod 4 and the decorative rod 5 are folded, the second lifting column 28 and the lightning cone 30 rise, and the lightning cone 30 extends out of the tower body 1.
