Abstract
Description
Technical Field
[0001] This invention relates to the technical field of environmental alarm systems, specifically an environmental alarm system based on wireless network applications. Background Technology
[0002] As is generally known, an environmental alarm system mainly consists of a data acquisition module, a data processing module, and an alarm module. The data acquisition module is responsible for collecting various parameters of a certain object in the environment; the data processing module processes and analyzes the collected data to determine whether the environment is in a normal state; the alarm module immediately issues an alarm when it detects an abnormality, reminding people to take appropriate measures.
[0003] As the material foundation for the development of the power industry, power grid facilities bear the responsibility of transmitting and distributing electrical energy. They are characterized by numerous points, wide coverage, long lines, and exposure to the elements. Therefore, damage to power grid facilities can cause operational problems. Regular inspections of power grid facilities are essential. For high-voltage power towers, manual climbing is not only extremely costly in terms of manpower and resources but also inefficient. To address this issue, existing technologies utilize drones to inspect high-voltage power towers from high altitudes. During the inspection, data is collected and analyzed in real time. When problems are detected, alarm signals are issued immediately, allowing for timely repairs by personnel.
[0004] For example, the invention patent application with publication number CN115360822A and publication date November 18, 2022, entitled "A Power Production and Distribution Safety Monitoring System Based on Unmanned Aerial Vehicle Inspection," describes a system where an unmanned inspection dispatch center is set up in the plant area, equipped with a host computer and a monitoring server. Each primary and secondary substation has an unmanned aerial vehicle (UAV) storage facility containing UAVs. These UAVs include a data storage and processing module, a GPS navigation module, a wireless signal communication unit I, an energy storage module, and a data acquisition module. The data storage and processing module and the energy storage module are equipped with data transmission interfaces and energy receiving units, respectively. Both high-voltage and low-voltage power tower groups have relay towers, and each relay tower has a UAV relay control platform connected to a solar energy storage unit, a relay power transmission unit, and a wireless signal communication unit II. This safety monitoring system is capable of systematic and interconnected safety monitoring of a large-scale power grid.
[0005] The shortcoming of existing technology is that the high height of high-voltage power towers and the air flow at high altitudes can disturb the rotors of drones during inspections, causing the rotation patterns of the drone's multiple rotors to become disordered. As a result, the drone is difficult to hover stably in a certain position, resulting in shaky and blurry images captured by the drone's camera unit. This makes it difficult for the data processing module to clearly analyze the data from the high-voltage power tower. Summary of the Invention
[0006] The purpose of this invention is to provide an environmental alarm system based on wireless network applications, thereby solving the technical problems in related technologies.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] An environmental alarm system based on wireless network applications includes a control center and multiple drones for monitoring power sites. Each drone communicates wirelessly with the control center. The system also includes a windproof module, which includes several windproof plates on the body of each drone. Each rotor of the drone corresponds to one windproof plate, and each windproof plate is arranged in a circumferential manner on the side of each rotor.
[0009] The aforementioned windproof plate is an elastic sheet.
[0010] The windproof module mentioned above also includes a plurality of first rods, each of which corresponds to a plurality of windproof plates. Each first rod is used to fix the position of the corresponding windproof plate. Under the driving force of the driving component, the first rods adjust the distance between the windproof plate and the rotor at the corresponding position.
[0011] As described above, the driving component includes a disc-shaped body rotatably disposed within the machine body, the disc-shaped body having a planar thread, and each first rod being screwed to the planar thread.
[0012] As mentioned above, each of the first rods is provided with two second rods. The first rod and the corresponding second rod are connected by a rack and pinion to transmit power. The two second rods adjust the curvature of the windproof plate in the length direction based on the movement force of the first rod.
[0013] As mentioned above, each of the second rods has a telescopic function.
[0014] As described above, the windproof plate has two adjustment slots, which are symmetrically arranged on both sides of the first rod. An adjustment rod is slidably installed in each adjustment slot, and an adjustment rod is fixedly connected to each second rod.
[0015] As described above, the adjusting rod includes a first section fixedly connected to the second rod body and a second section hinged to the first section. A first elastic element is provided at the hinge point between the first and second sections. The elastic force of the first elastic element makes the first and second sections tend to keep their axes aligned. A compression notch is provided at the hinge point between the first and second sections. A compression block is provided at one end of the adjusting groove near the connection between the first rod body and the windproof plate. When the compression notch is inserted into the corresponding compression block, the second section swings on the first section, and the windproof plate is bent in the width direction under the compression force of the second section.
[0016] As described above, the second rod body includes a first section connected to the adjusting rod and a second section hinged to the first section, the second section being rotatably mounted on the machine body; the first rod body includes an active section threaded to a plane and a driven section fixed to the wind deflector, the active section and the driven section being hinged, and the driven section being provided with a limiting member, the limiting member restricting the driven section from swinging on the active section; when the hinge axis of the first section and the second section coincides with the hinge axis of the active section and the driven section, the limiting member releases the swing restriction on the driven section, and it swings down under the gravity of the wind deflector to form the support leg of the machine body.
[0017] The aforementioned limiting member includes a limiting strip that is slidably disposed on the driven section, and a second elastic member is connected between the limiting strip and the driven section in the sliding direction. A slide rail is provided on the fuselage for the first rod to slide. When the center of the wind deflector after bending is on the same axis as the rotation center of the rotor, the limiting strip disengages from the slide rail and, under the action of the gravity of the wind deflector, the driven section swings up and down in the active section.
[0018] The beneficial effects of this invention are as follows: by setting a wind deflector on the side of each rotor, the airflow blowing from the side of the rotor can be blocked during the flight of the drone, so that the airflow can flow normally along the rotation axis of the rotor during the rotation of the rotor, thereby avoiding the problem of high-altitude airflow disturbing the rotation of the rotor from the side. This can reduce the problem of shaking and blurring of the images captured by the camera unit of the drone. Attached Figure Description

Detailed Implementation
[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 11 The present invention will now be described in further detail.
[0034] See Figures 1 to 10 As shown, in one embodiment of the present invention, an environmental alarm system based on a wireless network application is provided, including a control center and multiple drones for monitoring power field. Each drone communicates wirelessly with the control center. The system also includes a windproof module, which includes several windproof plates 3 disposed on the body of each drone. Each rotor 2 of the drone corresponds to one windproof plate 3, and each windproof plate 3 is disposed on the side of each rotor 2 in a circumferential surrounding manner.
[0035] Specifically, the drone's fuselage 1 is equipped with multiple cantilever arms, each with a power module. The power module drives the connected rotors 2 to rotate, generating lift to overcome the drone's own gravity and enabling it to take off. The drone's fuselage 1 is also equipped with a camera module, which is used to collect information from the power site. The camera module transmits the collected power site information to the control center via wireless communication. After receiving the power site information, the control center analyzes it and can promptly issue alarm signals when problems occur, so that staff can promptly detect problems at the power site and carry out timely repairs.
[0036] When using drones to monitor power sites, the location of the power site may present problems with turbulent airflow, especially in power sites located in plateau or mountainous areas. When monitoring high-voltage power towers at power sites, the unpredictable disturbances in airflow will inevitably affect the rotation of rotor 2. The take-off, ascent, and level flight of a drone all rely on the coordinated rotation of each rotor 2 according to a certain pattern to generate the power required for take-off, ascent, and level flight. When the rotation of rotor 2 is disturbed by airflow, the flight stability of the drone is disrupted, and the images captured by the camera module are prone to being blurry and shaky. Obviously, this situation is not conducive to the control center's analysis of power site information.
[0037] Based on the above problems, in this embodiment, a wind deflector 3 is provided in the circumferential direction of each rotor 2. The wind deflector 3 has an arc-shaped structure, but its radial dimension is larger than the radial dimension of the circular area formed by the rotor 2 when it rotates, so as to prevent frictional obstruction between the rotor 2 and the wind deflector 3. The wind deflector 3 does not obstruct the axial flow of gas when the rotor 2 rotates, but obstructs the airflow from the side to the rotor 2. In this way, the rotation of the rotor 2 can be basically unaffected by the airflow disturbance from the side.
[0038] The beneficial effect of this embodiment is that by setting a wind deflector 3 on the side of each rotor 2, the airflow blowing from the side of the rotor 2 can be blocked during the flight of the drone, so that the airflow can flow normally along the rotation axis of the rotor 2 during the rotation of the rotor 2, thereby avoiding the problem of high-altitude airflow disturbing the rotation of the rotor 2 from the side. This can reduce the problem of shaking and blurring of the images captured by the camera unit of the drone.
[0039] Preferably, the windproof plate 3 is an elastic sheet. Specifically, during flight, drones are inevitably subject to collisions with tree branches or birds. To avoid damaging the drone's rotor 2 and causing the drone to crash, in this embodiment, the windproof plate 3 is made of an elastic material and is made into a sheet shape, which does not affect wind protection and can also buffer the impact.
[0040] Preferably, the windproof module further includes a plurality of first rods 4, each of which corresponds to a plurality of windproof plates 3, and each first rod 4 is used to fix the position of the corresponding windproof plate 3. The first rod 4 adjusts the distance between the windproof plate 3 and the rotor 2 at the corresponding position under the driving force of the driving component. The driving component includes a disc-shaped body 5 rotatably disposed inside the machine body. The disc-shaped body 5 is provided with a planar thread, and each first rod 4 is screwed to the planar thread.
[0041] Specifically, as can be seen from the aforementioned embodiments, the wind deflector 3 has an elastic deformation function, which can buffer the impact. If the impact force is large, the deformation range of the wind deflector 3 will also increase. Thus, the deformation of the wind deflector 3 may impact the rotor 2. Therefore, in this embodiment, a first rod 4 is slidably arranged on each rotor 2 of the fuselage 1. One end of the first rod 4 is fixed to the wind deflector 3, and the other end is connected to the power output end of the drive component, that is, the disc 5 rotates (the rotation of the disc 5 is driven by a drive source such as a motor, which is prior art and will not be described in detail, and is not shown in the figure). The planar thread on the disc 5 applies a driving force to the other end of the screwed first rod 4 to move radially along the disc 5 (where the planar thread is prior art, and an example of its practical application is a triangular chuck). Thus, the movement of the first rod 4 can drive the wind deflector 3 to move closer to or away from the rotor 2. The radial dimension of the arc-shaped wind deflector 3 leaves sufficient distance, for example, the rotor 2 is in The circular area formed during rotation has a radial dimension of 10 units, while the arc-shaped wind deflector 3 has a radial dimension of 20 units. Thus, there is a 5-unit distance between the end of the rotor and the wind deflector 3, and the distance the wind deflector 3 is moved is between 0.5 and 4.5 units to avoid collisions with the rotor during the movement of the wind deflector 3. Therefore, a sensor is concentrated on the camera module to monitor the situation around the drone. When a foreign object approaches the drone, the disc 5 can rotate based on the sensor signal (the sensor is existing technology and will not be described in detail here), so that the planar thread gives the first rod 4 a radial force away from the disc 5. In this way, the first rod 4 drives the wind deflector 3 connected to it away from the rotor 2, so that the deformed wind deflector 3 will not collide with the rotor 2. After the wind deflector 3 returns to its original shape, the first rod 4 drives the wind deflector 3 back to the rotor 2 to continue to protect the rotor 2 from the wind.
[0042] Furthermore, each of the first rods 4 is provided with two second rods 6. The first rod 4 and the corresponding second rod 6 transmit power through the meshing of the rack 8 and the gear 7. The two second rods 6 adjust the curvature of the windproof plate 3 in the length direction based on the moving force of the first rod 4.
[0043] Specifically, two second rods 6 are positioned on either side of the width of the first rod 4, arranged in a V-shape. One end of each second rod 6 is rotatably mounted on the cantilever of the fuselage 1, with a gear 7 fixed to that end. The other end of each second rod 6 is connected to the wind deflector 3, meaning the other ends of the two second rods 6 correspond to the two ends of the wind deflector 3 along its length. A rack 8 is provided on the first rod 4, meshing with the gear 7 on the corresponding second rod 6. In the aforementioned embodiment, the movement of the first rod 4 can move the wind deflector 3 closer to or further away from the rotor 2, thus each second rod 6 has a telescopic function to adapt to changes in the position of the wind deflector 3. To facilitate adjustment of the curvature of the wind deflector 3, in this embodiment, two adjustment slots 9 are provided on the wind deflector 3. A rod 4 is symmetrically arranged on both sides, and an adjusting rod 10 is slidably installed in each adjusting groove 9. Each second rod 6 is fixedly connected to an adjusting rod 10. Thus, the movement of the first rod 4 drives the rack 8 connected to it to move together. The movement of the rack 8 drives the gear 7 meshing with it to rotate. The rotation of the gear 7 drives the second rod 6 fixed to it to swing. The swing of the second rod 6 drives the adjusting rod 10 connected to it to slide in the corresponding adjusting groove 9. The movement of the adjusting rod 10 applies a force to the inner wall of the adjusting groove 9, causing the windproof plate 3 to undergo elastic deformation. When the two adjusting rods 10 are close to the middle position of the windproof plate 3, the bending of the windproof plate 3 in the length direction is reduced by the force. Conversely, when the two adjusting rods 10 are away from the middle position of the windproof plate 3, the bending of the windproof plate 3 in the length direction is increased.
[0044] That is, the windproof plate 3 has a position with the greatest curvature and a position with the least curvature. When all the windproof plates 3 are in the position with the least curvature, they form a ring structure that surrounds the entire drone. The advantage of this setting is that when monitoring a certain point in the power field, the drone needs to hover. The ring structure can completely surround the side of the drone, preventing the drone from getting tangled with the cables in the power field when it is blown by the airflow.
[0045] Furthermore, the adjusting rod 10 includes a first segment 100 fixedly connected to the second rod body 6 and a second segment 101 hinged to the first segment 100. A first elastic element is provided at the hinge of the first segment 100 and the second segment 101. The elastic force of the first elastic element makes the first segment 100 and the second segment 101 tend to keep their axes aligned. A compression notch 11 is provided at the hinge of the first segment 100 and the second segment 101. A compression block 12 is provided at one end of the adjusting groove 9 near the connection between the first rod body 4 and the windproof plate 3. When the compression notch 11 is inserted into the corresponding compression block 12, the second segment 101 swings on the first segment 100. The windproof plate 3 is subjected to the compression force of the second segment 101 and bends in the width direction.
[0046] Specifically, at high altitudes, the force of airflow is significantly enhanced. Therefore, the wind deflector 3 should also have the effect of dispersing airflow. In this embodiment, the adjusting rod 10 is configured as a first segment 100 and a second segment 101 hinged together. The elastic potential energy of the first elastic element is greater than the elastic potential energy of the wind deflector 3. That is, under the action of external force, when the second segment 101 swings on the first segment 100, the second segment 101 will exert a compressive force on the wind deflector 3, causing the wind deflector 3 to tend to undergo elastic deformation in the width direction. When the external force applied to the second segment 101 is large enough, the wind deflector 3 can undergo elastic deformation in the width direction. That is, when the wind deflector 3 is needed... When the curvature in the length direction needs to be minimized, the adjusting rod 10 needs to be close to the middle of the wind deflector 3. During this process, the extrusion block 12 exerts an extrusion effect on the extrusion notch 11 at the hinge of the first section 100 and the second section 101. That is, the extrusion block 12 and the extrusion notch 11 exert an extrusion effect through the wedge-shaped engagement, so that the second section 101 swings on the first section 100 and exerts an extrusion effect on the deformation of the wind deflector 3 in the width direction. When the wind deflector 3 becomes arc-shaped in the width direction, and the arc-shaped arched surface is away from the fuselage 1, then when the airflow blows the wind deflector 3, the arc surface can disperse the airflow to the upper and lower sides, thereby reducing the impact of the airflow on the fuselage 1.
[0047] Furthermore, the second rod 6 includes a first section 60 connected to the adjusting rod 10 and a second section 61 hinged to the first section 60. The second section 61 is rotatably mounted on the body, and the extendable part of the second rod 6 is located on the first section 60. The first rod 4 includes an active section 40 threaded to a plane and a driven section 41 fixed to the wind deflector 3. The active section 40 and the driven section 41 are hinged, and the driven section 41 is provided with a limiting member. The limiting member restricts the driven section 41 from swinging on the active section 40. When the hinge axis of the first section 60 and the second section 61 coincides with the hinge axis of the active section 40 and the driven section 41, the limiting member releases the swing restriction on the driven section 41, and it swings down under the gravity of the wind deflector 3 to form the support leg of the body 1.
[0048] The limiting component includes a limiting strip 13 that is slidably disposed on the driven section 41, and a second elastic element is connected between the limiting strip 13 and the driven section 41 in the sliding direction. The fuselage 1 is provided with a slide rail 16 for the first rod 4 to slide. When the center of the wind deflector 3 after bending is on the same axis as the rotation center of the rotor 2, the limiting strip 13 disengages from the slide rail 16 and, under the action of the gravity of the wind deflector 3, the driven section 41 swings up and down in the active section 40.
[0049] Specifically, as can be seen from the aforementioned embodiments, the wind deflector 3 has a maximum and minimum curvature in the length direction. In this embodiment, the second rod 6 is configured as a first section 60 and a second section 61 that intersect each other, and the first rod 4 is configured as an active section 40 and a driven section 41 that are hinged together. When the curvature of the wind deflector 3 is not at its maximum position, the hinge axis of the first section 60 and the second section 61 does not coincide with the hinge axis of the active section 40 and the driven section 41, and the limiting member has not released the swing restriction on the driven section 41, then the wind deflector 3 cannot swing down under the action of gravity. That is, at this time, the limiting strip 13 is in the slide 16, and the swing of the driven section 41 is restricted. When the drone needs to land, it needs to land on an open ground. In this embodiment, during this process, the driving component drives the two second rods 6 through the first rod 4 to adjust the curvature of the wind deflector 3 to the maximum position, and makes the limiting strip 13 disengage from the restriction of the slide 16. Then the swing restriction of the driven section 41 disappears, and at this time the hinge axis of the first section 60 and the second section 61 coincides with the hinge axis of the active section 40 and the driven section 41. Then the wind deflector 3 can swing down under its own weight to form the foot when the drone lands. Thus, the additional drone foot can be eliminated, and the wind deflector 3 can replace the drone foot to support the landing drone.
[0050] To prevent the limiting strip 13 from being restricted by the slide rail 16, an opening can be provided at the position where the windproof plate 3 has the greatest curvature. That is, the width of the slide rail 16 at this position is greater than the width of the limiting strip 13. In this position, the limiting strip 13 is no longer restricted by the slide rail 16.
[0051] When the wind deflector 3 needs to return from its position as a replacement for the drone's foot to its upward position surrounding the rotor 2, the driven section 41 is pulled upward by the movement of the active section 40. That is, an inclined surface 14 is provided on each cantilever. The inclined surface 14 can save effort and has a small obstruction effect on the driven section 41, so that the active section 40 can smoothly pull the driven section 41 to a horizontal state. During this process, the wedge-shaped fit between the limiting strip 13 and the slide rail 16 generates a squeezing force that causes the limiting strip 13 to compress the second elastic element. After the limiting strip 13 is fully inserted into the slide rail 16, the limiting strip 13 is no longer squeezed. Under the rebound force of the second elastic element, the limiting strip 13 returns to its original position. At this time, the slide rail 16 restricts the limiting strip 13. This restriction does not affect the movement of the fiber strip with the driven section 41.
[0052] See Figure 11As shown in another embodiment of the present invention, as can be seen from the foregoing embodiments, when the sensor detects a foreign object approaching during the flight of the UAV, the drive component will drive the first rod 4 to push the wind deflector 3 away from the rotor 2 based on the sensor signal. In this embodiment, the second rod 6 adjusts the curvature of the wind deflector 3 based on the movement of the first rod 4. It can be seen that if the curvature of the wind deflector 3 decreases as it moves away from the rotor 2, the protection range of the wind deflector 3 will increase, thereby providing better protection for the rotor 2. Therefore, by adding a transmission gear 15 between the gear 7 and the rack 8, the above function can be achieved. At this time, at the position where the curvature of the wind deflector 3 is at its maximum, the position where the first rod 4 is screwed to the planar thread should be closest to the center of the disc-shaped body 5.
[0053] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.

The environmental alarm system based on wireless network application according to claim 5, characterized in that, The limiting component includes a limiting strip that slides on the driven section, and a second elastic element connects the limiting strip and the driven section in the sliding direction. The fuselage has a slide rail for the first rod to slide. When the center of the wind deflector after bending is on the same axis as the rotation center of the rotor, the limiting strip disengages from the slide rail and, under the action of the gravity of the wind deflector, the driven section swings up and down in the active section.
