The habitat monitoring device includes: a track with two opposing side walls, each with a guide groove; a main unit including a body and two transmission arms, each transmission arm being opposite to a corresponding guide groove and equipped with a guide wheel extending into the corresponding guide groove; a monitoring camera mounted on the body; and a brake block movably disposed at the end of at least one guide wheel.

Description

Technical Field

[0001] This application relates to the field of ecological monitoring technology, and in particular to a habitat monitoring device for power transmission and transformation line areas. Background Technology

[0002] Transmission lines significantly impact biological habitats through direct damage, indirect disturbance, and alteration of the microenvironment. Habitat restoration is necessary to restore critical habitat functions and ensure the long-term safe operation of the power grid. Therefore, the ecological restoration process requires real-time monitoring. By utilizing a self-propelled habitat monitoring device that periodically moves along a pre-set track, the monitoring camera on the device takes pictures of the surrounding environment of the transmission line area. Analyzing the habitat conditions in the photographic samples can determine whether the habitat status of the transmission line area has changed.

[0003] In related technologies, in order to facilitate comparison of habitat changes in power transmission and transformation line areas over a period of time, and to facilitate the stitching of multiple consecutive photos taken by the habitat monitoring device, the habitat monitoring device should ideally take photos at the same position and shooting angle. That is, the main unit of the habitat monitoring device needs to stop precisely at the preset shooting position on the track. However, when there are impurities such as dust and oil on the track, the main unit is prone to slipping, causing the actual stopping position of the main unit to deviate from the preset shooting position. Chinese patent application CN116423532A discloses a track inspection robot. This track inspection robot increases the clamping force between the walking wheels and the track to increase the friction between the walking wheels and the track, thereby preventing the robot body from slipping. However, the contact between the walking wheels and the track is a line contact, and the contact area between the walking wheels and the track is small. Even if the clamping force between the walking wheels and the track is increased, the increase in friction between the walking wheels and the track is limited, and the slipping problem still exists between the main unit and the track. Summary of the Invention

[0004] The purpose of this application is to increase the friction between the host and the track when the host reaches or approaches the preset shooting position relative to the track, so that the host stops precisely at the preset shooting position, thereby enabling the monitoring camera on the habitat monitoring device to take pictures and sample the surrounding environment of the power transmission and transformation line area at the preset shooting position and preset shooting angle.

[0005] To achieve the above objectives, this application provides a habitat monitoring device for power transmission and transformation line areas.

[0006] The habitat monitoring device for power transmission and transformation line areas according to this application includes: a track extending along a first direction, the track including at least two sidewalls spaced apart along a second direction, each of the two sidewalls having a guide groove recessed toward the track, the guide groove extending toward the first direction, wherein the first direction and the second direction are perpendicular to each other; a main unit, the main unit including a body and a plurality of transmission arms connected to each other, the body being adapted to move along the track, one of the transmission arms being disposed opposite to one of the guide grooves, another transmission arm being disposed opposite to another guide groove, each of the sidewalls of the plurality of transmission arms opposite to the corresponding guide grooves having a guide wheel, the guide wheel extending into the corresponding guide groove, the outer peripheral wall of the guide wheel abutting and guidingly engaging with the groove wall of the corresponding guide groove; A monitoring camera is mounted on the body; at least one braking block is located on the outer side of the guide wheel away from the corresponding transmission arm, and a braking groove is provided at the bottom of the corresponding guide groove. The braking block moves along the axial direction of the guide wheel and extends into the braking groove, so that the side wall of the braking block contacts the groove wall surface of the braking groove to brake the host. The momentum of the host is p, the braking distance of the host is d, the moving speed of the host is v, the coefficient of friction between the track and the host is μ, the weight of the host is m, the gravitational acceleration is g, and the minimum braking force is Fmin. d, p, v, μ, m, g and Fmin satisfy the relationship: v / (2μmg)≤d / p≤v / (2Fmin).

[0007] According to the habitat monitoring device for power transmission and transformation line areas disclosed in this application, a brake block is provided at the end of the guide wheel. When the main unit reaches or approaches the preset photographing position relative to the track, the brake block is inserted into the brake groove to contact the surface of the brake groove. This results in a larger contact area between the main unit and the track, and a greater braking force can be generated between the brake block and the brake groove. This improves the braking performance of the main unit and enables it to stop precisely at the preset photographing position. Consequently, the monitoring camera on the habitat monitoring device can take pictures and sample the surrounding environment of the power transmission and transformation line area at the preset photographing position and at a preset photographing angle. This facilitates the comparison of changes in the surrounding habitat of the power transmission and transformation line area over a period of time.

[0008] In some examples of this application, the width of the brake groove gradually decreases from the opening of the brake groove to the bottom of the brake groove, and the sidewall of the brake block that contacts the brake groove is provided with a slope so that the sidewall of the brake block matches the groove wall of the brake groove. The width direction of the brake groove, the first direction and the second direction are mutually perpendicular.

[0009] In some examples of this application, the brake block is constructed as a magnetic element having two magnetic poles of opposite polarity, forming a closed magnetic field between the two magnetic poles, and the two magnetic poles are arranged along a third direction, wherein the first direction, the second direction, and the third direction are mutually perpendicular.

[0010] In some examples of this application, the host is provided with a transmission assembly, which is disposed between the brake block and the corresponding transmission arm. The transmission assembly includes a transmission sleeve shaft and a telescopic member. The transmission sleeve shaft extends along the second direction and includes an outer sleeve and an inner shaft body. The outer sleeve is sleeved on the outside of the inner shaft body. In the axial direction of the transmission sleeve shaft, one end of the outer sleeve is coaxial with and fixedly connected to the guide wheel, and the other end of the outer sleeve is rotatably inserted into the transmission arm. One end of the inner shaft body passes through the guide wheel and is fixedly connected to the brake block. The other end of the inner shaft body is connected and cooperated with the telescopic member. The telescopic member is installed on the transmission arm. By extending or retracting the telescopic member, the telescopic member drives the inner shaft body to move relative to the outer sleeve in the axial direction of the transmission sleeve shaft, thereby causing the brake block to extend into or move out of the brake groove.

[0011] In some examples of this application, the transmission assembly further includes a reset member disposed between the inner shaft and the outer bushing. The reset member is used to drive the inner shaft along the axial direction of the transmission sleeve shaft to move the brake block out of the brake groove.

[0012] In some examples of this application, the outer peripheral wall of the inner shaft is provided with a first stop edge, the first stop edge being located at the end of the inner shaft extending into the transmission arm; the outer peripheral wall of the outer bushing is provided with a second stop edge, the second stop edge being located at the end of the outer bushing extending into the transmission arm; the first stop edge and the second stop edge are spaced apart along the axial direction of the transmission sleeve shaft; the reset member is constructed as a helical spring, the helical spring being sleeved on the outer peripheral side of the inner shaft, and the helical spring being elastically deformable and supported between the first stop edge and the second stop edge; the second stop edge is adapted to abut and limit the engagement with the side wall of the transmission arm.

[0013] In some examples of this application, the body includes an outer shell and a drive assembly. The drive assembly is mounted in the outer shell and includes a drive member and a drive gear. The drive member is pulsatorically connected to the drive gear and is used to drive the drive gear to rotate about the central axis of the drive gear. The drive gear extends at least partially out of the outer shell. In a third direction, the sidewall of the track opposite to the body is provided with a toothed groove. The toothed groove extends along the first direction and has a first tooth. The drive gear has a second tooth. The first tooth and the second tooth mesh with each other. The first direction, the second direction, and the third direction are mutually perpendicular.

[0014] In some examples of this application, the drive assembly further includes an input shaft, an output shaft, and a clutch. The clutch includes a first clutch portion and a second clutch portion that engage with each other and are coaxially arranged. The input shaft is connected between the first clutch portion and the output end of the drive assembly, and the output shaft is connected between the second clutch portion and the drive gear. The first clutch portion has a first end wall, and the second clutch portion has a second end wall. The first end wall and the second end wall are disposed opposite to each other. One of the first end wall and the second end wall is provided with a stop block protruding towards the other. The other of the first end wall and the second end wall is provided with a stop groove. The stop block extends into the stop groove, and the stop block abuts against the groove wall of the stop groove.

[0015] In some examples of this application, the first end wall is provided with the stop block, and the second end wall is provided with a plurality of limiting strips. The limiting strips are constructed as flexible members that can be contracted and deformed inward. The limiting strips extend along the circumference of the clutch member, and at least two of the limiting strips are spaced apart along the circumference of the clutch member to form the stop groove.

[0016] In some examples of this application, the habitat monitoring device for power transmission and transformation line areas further includes: a photoelectric sensor, which includes a transmitting and receiving unit and a reflecting unit. Along the axial direction of the clutch, the transmitting and receiving unit is located on one side of the clutch, and the reflecting unit is located on the other side of the clutch. Both the transmitting and receiving unit and the reflecting unit are spaced apart from the clutch and are arranged opposite to each other. The first clutch portion has a first through hole, and the second clutch portion has a second through hole. The first through hole and the second through hole are configured such that when the stop block is located within the stop groove, the first through hole communicates with the second through hole, allowing light to be transmitted between the transmitting and receiving unit and the reflecting unit.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a brake block at the end of the guide wheel, when the main unit reaches or approaches the preset shooting position relative to the track, the brake block is inserted into the brake groove to contact the surface of the brake groove. The main unit and the track have a larger contact area, and the brake block and the brake groove can generate a larger braking force, which can improve the braking performance of the main unit and enable the main unit to stop accurately at the preset shooting position. This allows the monitoring camera on the habitat monitoring device to take pictures and sample the surrounding environment of the power transmission and transformation line area at the preset shooting position and preset shooting angle, which facilitates the habitat monitoring device to compare the changes in the surrounding habitat of the power transmission and transformation line area over a period of time.

[0018] 2. Under the influence of magnetic force, when the brake block detaches from the brake groove, due to the magnetic properties of the brake block, the magnetic permeability distribution in the magnetic circuit formed between the magnetic moment of the brake block and the metal material near the groove wall or opening is uneven. This results in the brake block having a stable posture with the lowest magnetic energy when approaching the brake groove. When the brake block is deflected by an external force, its magnetic potential energy increases. The magnetic field generated by the brake block produces a rotational torque, which returns the brake block to its magnetically stable posture. This design ensures that the brake block is always aligned with the brake groove, thus preventing the brake block from deflecting or displacing relative to the brake groove.

[0019] 3. After the stop block extends into the stop groove, the limiting strips located on both sides of the stop block in the circumferential direction of the clutch can limit the stop block. The first clutch part can drive the second clutch part to rotate by driving the stop block. Furthermore, by setting the limiting strip as a flexible element and making the stop block and the limiting strip abut against each other, the limiting strip can be slightly deformed when the stop part squeezes the limiting strip. When the driving part is stationary, the elastic force generated by the limiting strip after being compressed can make the driving gear and the tooth groove be in a meshing state, thereby reducing the error caused by the gap between the driving gear and the tooth groove in the position calculation of the main unit relative to the track.

[0020] 4. When the first through hole and the second through hole are connected, and the first clutch rotates to the point where the first through hole is opposite the transmitting and receiving unit, the light emitted by the transmitting and receiving unit can pass through the first and second through holes and illuminate the reflecting unit. The light reflected by the reflecting unit also passes through the first and second through holes and illuminates the transmitting and receiving unit. When the transmitting and receiving unit can receive its emitted light, it proves that the stop block is located within the stop groove, the first and second clutches are not misaligned, and the limiting strip is not excessively compressed. Conversely, when the transmitting and receiving unit cannot receive its emitted light, it proves that the stop block is located outside the stop groove, the first and second clutches are misaligned, and the limiting strip is excessively compressed.

[0023] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0024] like Figures 1-7 As shown in the figure, this application discloses a habitat monitoring device 100 for power transmission and transformation line areas. The habitat monitoring device 100 is used to monitor the surrounding habitat of the power transmission and transformation line area. Specifically, the habitat monitoring device 100 can monitor the vegetation coverage and vegetation diversity around the power transmission and transformation line area.

[0025] like Figures 1-5 As shown, the habitat monitoring device 100 according to an embodiment of this application includes: a track 1 and a main unit 2, a monitoring camera 4, and at least one braking block. The main unit 2 is movable along the track 1. The monitoring camera 4 is mounted on the main unit 2. The monitoring camera 4 can be an AI camera. The monitoring camera 4 is used to take pictures of the environment around the main unit 2, and the monitoring camera 4 can determine the vegetation coverage and vegetation diversity of the environment around the main unit 2 based on the pictures. The main unit 2 can drive the monitoring camera 4 to move, thereby increasing the shooting range of the monitoring camera 4. Furthermore, the monitoring camera 4 can rotate around the rotation axis at the connection between the monitoring camera 4 and the main unit 2 to adjust the shooting angle of the monitoring camera 4.

[0026] Track 1 extends along a first direction, which can refer to... Figure 5 In the left-right direction. In a specific embodiment of this application, the track 1 can be installed on the power transmission tower 200, and the track 1 can be installed on one of the side walls of the power transmission tower 200. The track 1 can also surround the outer periphery of the power transmission tower 200. In this case, an arc-shaped transition track 17 is connected between any two adjacent side walls of the power transmission tower 200. The arc-shaped transition track 17 protrudes towards the outer periphery of the power transmission tower 200. The arc-shaped transition track 17 is used to allow the host 2 to smoothly move from one side wall of the power transmission tower 200 to its adjacent side wall. The specific arrangement of the track 1 can be set according to the actual terrain environment around the power transmission tower 200.

[0027] The power transmission tower 200 has a relatively high height. By setting the track 1 close to the top of the power transmission tower 200, the installation height of the main unit 2 can be increased, the shooting field of the monitoring camera 4 can be increased, and the monitoring camera 4 can be prevented from being blocked, thereby improving the monitoring effect of the habitat monitoring device 100.

[0028] Furthermore, such as Figure 3 As shown, track 1 includes at least two sidewalls opposite each other along the second direction, such as Figure 3 As shown, the two sidewalls are a first sidewall 15 and a second sidewall 16, respectively. Both sidewalls of the track 1 are provided with guide grooves 11 that are recessed into the track 1. The guide grooves 11 extend in a second direction, wherein the first direction and the second direction are perpendicular to each other, and the second direction can refer to... Figure 3 The vertical direction is one direction, and the second direction can be the same as the height direction of the power transmission and transformation tower 200.

[0029] Furthermore, the main unit 2 includes an interconnected body 21 and multiple transmission arms 22. A drive assembly 7 is disposed within the body 21, and the body 21 is adapted to move along the track 1 via the drive assembly 7. The specific structure of the drive assembly 7 will be described in detail below. One transmission arm 22 is positioned opposite to one guide groove 11, and the other transmission arm 22 is positioned opposite to another guide groove 11. That is, the two transmission arms 22 are positioned opposite each other and spaced apart along a second direction, forming a receiving gap between the two transmission arms 22, and the track 1 is located within the receiving gap.

[0030] Each of the multiple transmission arms 22 has a guide wheel 3 on its sidewall opposite to the corresponding guide groove 11. The guide wheel 3 extends into the corresponding guide groove 11, and its outer peripheral wall abuts against and guides the groove wall of the corresponding guide groove 11. The central axis of the guide wheel 3 extends along the second direction. When the machine body 21 moves along the track 1, the guide wheel 3 rotates around its central axis. The cooperation between the guide wheel 3 and the guide groove 11 makes the movement of the machine body 21 more stable. At the same time, the guide wheel 3 and the guide groove 11 abut against and limit the movement of the machine body 21 relative to the track 1 in the second and third directions, thereby preventing the machine body 21 from detaching from the track 1. The first, second, and third directions are all perpendicular to each other.

[0031] In some preferred embodiments, such as Figure 3 , Figure 4 As shown, the guide wheel 3 can be truncated cone in shape. The outer diameter of the end face of the guide wheel 3 near the transmission arm 22 is larger than the outer diameter of the end face of the guide wheel 3 away from the transmission arm 22. This arrangement can improve the pressing effect between the guide wheel 3 and the groove wall of the guide groove 11.

[0032] Furthermore, at least one transmission arm 22 is provided with multiple guide wheels 3, which are arranged sequentially along the first direction. The multiple guide wheels 3 located on the same side of the track 1 all abut against the groove wall of the guide groove 11, which can restrict the main unit 2 from rotating when it moves along the track 1, thereby making the movement direction and movement path of the machine body 21 more stable.

[0033] Furthermore, such as Figure 3 , Figure 4 As shown, the brake block 5 is located on the outer side of the end of the guide wheel 3 away from the corresponding transmission arm 22, that is, Figure 3A brake block 5 is provided at the end of the guide wheel 3 near the upper end of the main body 21, or at the end of the guide wheel 3 near the lower end of the main body 21, or at the ends of both the upper and lower ends of the guide wheel 3. A brake groove 12 is provided at the bottom of the corresponding guide groove 11. The brake groove 12 extends in the same direction as the guide groove 11, i.e., the brake groove 12 extends along a first direction. The brake block 5 moves axially along the guide wheel 3 and extends into the brake groove 12, causing the sidewall of the brake block 5 to contact the groove wall of the brake groove 12, thereby braking the main body 2. The momentum of the main body 2 is p, the braking distance of the main body 2 is d, the moving speed of the main body 2 is v, the coefficient of friction between the track 1 and the main body 2 is μ, the weight of the main body 2 is m, the gravitational acceleration is g, and the minimum braking force is F. min, the minimum braking force Fmin refers to the minimum braking force that the host 2 can generate when braking. d, p, v, μ, m, g and Fmin satisfy the relationship: v / (2μmg)≤d / p≤v / (2Fmin). In this way, by increasing the braking force of the host 2, the ratio of the braking distance to the momentum of the host 2 satisfies the above relationship. After receiving the braking command, the host 2 can complete the braking operation faster, and the difference between the actual parking position of the host 2 and the preset shooting position can meet the relevant error requirements.

[0034] Therefore, by setting a brake block 5 at the end of the guide wheel 3, when the host 2 reaches or approaches the preset shooting position relative to the track 1, the brake block 5 is inserted into the brake groove 12 to contact the surface of the brake groove 12. The host 2 and the track 1 have a larger contact area, and the brake block 5 and the brake groove 12 can generate a larger braking force, which can improve the braking performance of the host 2 and enable the host 2 to stop accurately at the preset shooting position. This allows the monitoring camera 4 on the habitat monitoring device 100 to take pictures and sample the surrounding environment of the power transmission and transformation line area at the preset shooting position and preset shooting angle, thereby facilitating the habitat monitoring device 100 to compare the changes in the surrounding habitat of the power transmission and transformation line area over a period of time.

[0035] like Figure 3 , Figure 4 As shown, in some embodiments of this application, the width of the brake groove 12 gradually decreases from the open end to the bottom of the brake groove 12. The sidewall of the brake block 5 that contacts the brake groove 12 is correspondingly set as an inclined surface so that the sidewall of the brake block 5 matches the groove wall of the brake groove 12. The width direction, the first direction, and the second direction of the brake groove 12 are mutually perpendicular. The width direction of the brake groove 12 can be referred to as... Figure 3The front-to-back direction, that is, the third direction, is the same as the width direction of the brake groove 12. Specifically, by setting the sidewall of the brake block 5 that contacts the brake groove 12 as an inclined surface, the width of the brake block 5 gradually increases from the end of the brake block 5 away from the transmission arm 22 to the end closer to the transmission arm 22. The width direction of the brake block 5 is the same as the width direction of the brake groove 12, and the width of the end of the brake block 5 away from the transmission arm 22 is smaller than the width of the open part of the brake groove 12. This design makes it easier for the brake block 5 to extend into the brake groove 12. When the brake block 5 is slightly misaligned with the brake groove 12, the brake block 5 can be smoothly inserted into the brake groove 12, thereby preventing the brake block 5 from failing.

[0036] Furthermore, the brake block 5 and the brake groove 12 can form a more stable surface contact. When there are impurities such as dust or oil on the groove wall of the brake groove 12, the brake block 5 and the groove wall of the brake groove 12 are less likely to wobble laterally when they stop, which can improve the fit between the brake block 5 and the groove wall of the brake groove 12. This can further increase the braking force between the host 2 and the track 1, and ensure that the host 2 stops accurately at the preset photo position.

[0037] Furthermore, the brake block 5 is constructed as a magnetic component with two opposite magnetic poles forming a closed magnetic field, and the two poles are arranged along a third direction. Under the action of magnetic force, when the brake block 5 detaches from the brake groove 12, due to the magnetism of the brake block 5, the magnetic permeability distribution of the magnetic circuit formed between the magnetic moment of the brake block 5 and the metal material near the groove wall or opening of the brake groove 12 is uneven. This results in the brake block 5 having a stable posture with the lowest magnetic energy when close to the brake groove 12. When the brake block 5 is deflected by an external force, its magnetic potential energy increases, and the magnetic field generated by the brake block 5 produces a rotational torque. This rotational torque can return the brake block 5 to a magnetically stable posture. This arrangement ensures that the brake block 5 is always aligned with the brake groove 12, thereby preventing the brake block 5 from deflecting or displacing relative to the brake groove 12. This also avoids misalignment between the brake block 5 and the brake groove 12, which could prevent the brake block 5 from being inserted into the brake groove 12, thus improving the braking reliability of the brake block 5.

[0038] like Figure 3 As shown, in some embodiments of this application, the host 2 is provided with a transmission assembly 6, which is disposed between the brake block 5 and the corresponding transmission arm 22. The transmission assembly 6 includes a transmission sleeve shaft 61 and a telescopic member 62. The transmission sleeve shaft 61 is along the second direction (i.e., Figure 3The transmission sleeve shaft 61 extends vertically (in the vertical direction) and includes an outer sleeve 611 and an inner shaft body 612. The outer sleeve 611 is fitted outside the inner shaft body 612, and the inner shaft body 612 can move relative to the outer sleeve 611 along the axial direction of the transmission sleeve shaft 61. Along the axial direction of the transmission sleeve shaft 61, one end of the outer sleeve 611 is coaxially and fixedly connected to the guide wheel 3, and the other end of the outer sleeve 611 is rotatably inserted into the transmission arm 22. The guide wheel 3 can be indirectly connected to the transmission arm 22 through the outer sleeve 611. Furthermore, when the main unit 2 moves along the track 1, and the guide wheel 3 rotates relative to the transmission arm 22 along its central axis, the outer sleeve 611 can rotate with the guide wheel 3 relative to the transmission arm 22, thereby ensuring that the guide wheel 3 does not jam when rotating. Of course, in some other embodiments, by providing a bearing between the outer sleeve 611 and the guide wheel 3, the rotation of the guide wheel 3 can be made smoother.

[0039] Furthermore, one end of the inner shaft 612 is fixedly connected to the brake block 5, and the other end of the inner shaft 612 is connected and cooperated with the telescopic member 62. It should be noted that the guide wheel 3 may be provided with a clearance hole that runs through it along its axial direction. The inner shaft 612 passes through the clearance hole to connect and cooperate with the brake block 5. The telescopic member 62 is installed on the transmission arm 22. By extending or retracting the telescopic member 62, the telescopic member 62 drives the inner shaft 612 to move relative to the outer bushing 611 along the axial direction of the transmission sleeve shaft 61, so as to drive the brake block 5 to extend into or move out of the brake groove 12.

[0040] The telescopic component 62 can be constructed as a cylinder, hydraulic cylinder, or electric strut, etc. Furthermore, in... Figure 3 In the illustrated embodiment, the telescopic member 62 can be installed on the outside of the transmission arm 22 and extend into the transmission arm 22 to connect and cooperate with the inner shaft 612. This design reduces the space occupied by the telescopic member 62 within the transmission arm 22, thereby making the height of the transmission arm 22 smaller and facilitating its carrying and assembly by installers in the field. However, this application is not limited to this; the telescopic member 62 can also be installed inside the transmission arm 22 and directly connected and cooperate with the inner shaft 612. The outer wall of the transmission arm 22 can provide protection for the telescopic member 62, thereby extending its service life.

[0041] By using the outer bushing 611 to limit the inner shaft 612, the outer bushing 611 can restrict the radial movement of the inner shaft 612 along the transmission sleeve shaft 61. This allows the inner shaft 612 to be driven by the telescopic member 62 to precisely insert the brake block 5 into the brake groove 12, preventing the brake block 5 from shifting during movement. This further avoids misalignment between the brake block 5 and the brake groove 12, which would prevent the brake block 5 from being inserted into the brake groove 12, and further improves the braking reliability of the brake block 5.

[0042] like Figure 3As shown, in some embodiments of this application, the transmission assembly 6 further includes a reset member 63, which is disposed between the inner shaft 612 and the outer bushing 611. The reset member 63 is used to drive the inner shaft 612 to move the brake block 5 out of the brake groove 12 along the axial direction of the transmission sleeve shaft 61. When the machine body 21 completes braking and the driving force applied to the brake block 5 by the telescopic member 62 towards the brake groove 12 disappears, by using the reset member 63 to drive the brake block 5 out of the brake groove 12, the side wall of the brake block 5 can be separated from the groove wall of the brake groove 12, thereby reducing the braking force between the main unit 2 and the track 1, and allowing the main unit 2 to move smoothly relative to the track 1.

[0043] Furthermore, such as Figure 3 , Figure 4 As shown, the outer peripheral wall of the inner shaft body 612 is provided with a first retaining edge 613, which is located at the end of the inner shaft body 612 that extends into the transmission arm 22. The outer peripheral wall of the outer bushing 611 is provided with a second retaining edge 614, which is located at the end of the outer bushing 611 that extends into the transmission arm 22. The first retaining edge 613 and the second retaining edge 614 are along the axial direction of the transmission sleeve shaft 61 (i.e., Figure 3 The distance between the first and second stops 613 and 614 gradually increases as the brake block 5 moves outward toward the brake groove 12, and gradually decreases as the brake block 5 is inserted into the brake groove 12.

[0044] The reset component 63 is constructed as a helical spring, which is sleeved on the outer periphery of the inner shaft 612. The helical spring is elastically deformable and supported between the first stop 613 and the second stop 614. When the telescopic component 62 extends and drives the inner shaft 612 to insert the brake block 5 into the brake groove 12, the distance between the first stop 613 and the second stop 614 decreases, the helical spring is compressed and generates elastic force. At this time, the magnitude of the elastic force is less than the magnitude of the driving force of the telescopic component 62, which can ensure that the brake block 5 and the groove wall of the brake groove 12 are in a stop-fitting engagement to brake the main unit 2. When the telescopic component 62 no longer generates driving force, under the action of the elastic force, the helical spring returns to its deformation and drives the first stop 613 to move away from the second stop 614. Then, the first stop 613 drives the inner shaft 612 to move the brake block 5 in a direction away from the brake groove 12, which can separate the brake block 5 from the groove wall of the brake groove 12. The main unit 2 is no longer braked and can move along the track 1.

[0045] Furthermore, such as Figure 3 , Figure 4As shown, the second stop 614 is adapted to abut and limit the movement of the side wall of the transmission arm 22. This arrangement prevents the outer bushing 611 from dislodging from the transmission arm 22, thereby improving the reliability of the connection between the guide wheel 3 and the transmission arm 22. Furthermore, when the extension dimension of the telescopic member 62 is at its minimum, the helical spring can be in a pre-compressed state. The elastic force generated by the helical spring in the pre-compressed state can keep the second stop 614 pressed against the side wall of the transmission arm 22. This can prevent the outer bushing 611 and the guide wheel 3 from jumping along the axial direction of the transmission sleeve shaft 61, thereby further improving the stability of the main unit 2 when moving along the track 1.

[0046] like Figure 3 , Figure 5 As shown, in some embodiments of this application, the body 21 includes an outer shell 211 and a drive assembly 7. The drive assembly 7 is installed inside the outer shell 211. The outer shell 211 is fixedly connected to the housing of the transmission arm 22. In some preferred embodiments, the outer shell 211 and the housing of the transmission arm 22 are integrally formed. It can also be understood that the part of the outer shell 211 protruding towards the track 1 in a third direction forms the transmission arm 22.

[0047] Drive assembly 7 includes a drive element 71 and a drive gear 72, in Figure 3 In the illustrated embodiment, the drive component 71 can be a motor. The drive component 71 is connected to the drive gear 72 for transmission. The drive component 71 drives the drive gear 72 to rotate around the central axis of the drive gear 72. The drive gear 72 extends at least partially outside the outer casing 211. In a third direction, the side wall of the track 1 opposite to the body 21 is provided with a toothed groove 13. The toothed groove 13 extends along a first direction and has a first tooth. The drive gear 72 has a second tooth, and the first tooth and the second tooth mesh with each other. By moving the drive gear 72 along the toothed groove 13, the technical effect of the main unit 2 moving relative to the track 1 can be achieved.

[0048] Furthermore, the host unit 2 and the track 1 are connected by a gear structure. The movement distance of the host unit 2 can be determined based on the number of teeth moved by the drive gear 72 on the tooth groove 13. This facilitates the habitat monitoring device 100 in accurately controlling the position of the host unit 2 on the track 1, thereby further reducing the deviation between the actual stopping position of the host unit 2 and the preset imaging position. This allows the habitat monitoring device 100 to compare the changes in the surrounding habitat of the power transmission line area over a period of time, thus improving the monitoring accuracy of the habitat monitoring device 100. In addition, compared to setting a drive wheel on the host unit 2, the drive wheel directly contacts the track 1, and slippage between the drive gear 72 and the tooth groove 13 is less likely to occur, thereby further improving the displacement accuracy of the host unit 2.

[0049] Furthermore, such as Figure 3As shown, in the second direction, limiting flanges 14 can be provided on both sides of the tooth groove 13. The limiting flanges 14 are adapted to stop and limit the drive gear 72, thereby preventing the drive gear 72 from moving in the second direction and disengaging from the tooth groove 13, and also preventing the drive gear 72 from deflecting relative to the tooth groove 13, thus improving the connection reliability between the drive gear 72 and the tooth groove 13. Furthermore, the surface of the tooth groove 13 in contact with the drive gear 72 is provided with a lubricating coating. The lubricating coating can be formed by applying lubricating oil or grease to the tooth groove 13. The lubricating coating can reduce the friction between the drive gear 72 and the tooth groove 13, making the drive gear 72 run more smoothly and preventing the drive gear 72 from jamming.

[0050] like Figure 3 As shown, in some embodiments of this application, the drive assembly 7 further includes an input shaft 73, an output shaft 74, and a clutch 75. The clutch 75 includes a first clutch portion 751 and a second clutch portion 752 that are engaged with each other and coaxially arranged. The input shaft 73 is connected between the first clutch portion 751 and the output end of the drive assembly 71, and the output shaft 74 is connected between the second clutch portion 752 and the drive gear 72. After the drive assembly 71 outputs power, the power is sequentially output to the drive gear 72 through the input shaft 73, the first clutch portion 751, the second clutch portion 752, and the output shaft 74. In some preferred embodiments, the drive assembly 71, the input shaft 73, the clutch 75, the output shaft 74, and the drive gear 72 are all coaxially arranged. This arrangement can make the structure of the host 2 more compact and make the force transmission between the drive assembly 71 and the drive gear 72 more stable.

[0051] The first clutch portion 751 has a first end wall 753, and the second clutch portion 752 has a second end wall 754. The first end wall 753 and the second end wall 754 are disposed opposite to each other. Figure 7 In the illustrated embodiment, the first end wall 753 can be the lower end wall of the first clutch portion 751, and the second end wall 754 can be the upper end wall of the second clutch portion 752. One of the first end wall 753 and the second end wall 754 is provided with a stop block 76 protruding towards the other, and the other end wall 753 and the second end wall 754 are provided with a stop groove 77. The stop block 76 extends into the stop groove 77, and the stop block 76 abuts against the groove wall of the stop groove 77.

[0052] Furthermore, such as Figure 6 , Figure 7As shown, a stop block 76 is provided on the first end wall 753, and a plurality of limiting strips 78 are provided on the second end wall 754. The limiting strips 78 can be constructed as flexible members that can contract and deform inward. Specifically, the limiting strips 78 can be made of rubber. The limiting strips 78 extend circumferentially along the clutch member 75, and at least two limiting strips 78 are spaced apart circumferentially along the clutch member 75 to form a stop groove 77. After the stop block 76 extends into the stop groove 77, the limiting strips 78 located on both sides of the stop block 76 can limit the stop block 76 in the circumferential direction of the clutch member 75. The first clutch part 751 can drive the second clutch part 752 to rotate by driving the stop block 76. Furthermore, by setting the limiting strip 78 as a flexible element and making the stop block 76 abut against the limiting strip 78, the limiting strip 78 can be slightly deformed when the stop block squeezes the limiting strip 78. When the driving member 71 is stationary, the elastic force generated by the limiting strip 78 after being pressed can make the driving gear 72 and the tooth groove 13 be in a meshing state, thereby reducing the error in the position calculation of the host 2 relative to the track 1 caused by the gap between the driving gear 72 and the tooth groove 13.

[0053] like Figure 3 , Figure 5 , Figure 6 As shown, in some embodiments of this application, the habitat monitoring device 100 may further include: a photoelectric sensor 8, which includes a transmitting and receiving unit 81 and a reflecting unit 82. On the axial direction of the clutch 75, the transmitting and receiving unit 81 is located on one side of the clutch 75, and the reflecting unit 82 is located on the other side of the clutch 75. The transmitting and receiving unit 81 and the reflecting unit 82 are both spaced apart from the clutch 75 and are arranged opposite to each other. The transmitting and receiving unit 81 is used to emit light to the reflecting unit 82, and the light is reflected by the reflecting unit 82 and returns to the transmitting and receiving unit 81.

[0054] The first clutch portion 751 is provided with a first through hole 755, and the second clutch portion 752 is provided with a second through hole 756. The first through hole 755 and the second through hole 756 are configured such that when the stop block 76 is located in the stop groove 77, the first through hole 755 and the second through hole 756 are connected, so that light can be transmitted between the transmitting and receiving unit 81 and the reflecting unit 82. When the first through hole 755 is connected to the second through hole 756, the first clutch part 751 rotates until the first through hole 755 is opposite to the transmitting and receiving unit 81. The light emitted by the transmitting and receiving unit 81 can pass through the first through hole 755 and the second through hole 756 and illuminate the reflecting unit 82. The light reflected by the reflecting unit 82 also passes through the first through hole 755 and the second through hole 756 and illuminates the transmitting and receiving unit 81. When the transmitting and receiving unit 81 can receive its emitted light, it proves that the stop block 76 is located within the stop groove 77, the first clutch part 751 and the second clutch part 752 are not misaligned, and the limiting strip 78 is not excessively compressed. Conversely, when the transmitting and receiving unit 81 cannot receive its emitted light, it proves that the stop block 76 is located outside the stop groove 77, the first clutch part 751 and the second clutch part 752 are misaligned, and the limiting strip 78 is excessively compressed.

[0055] In some specific embodiments of this application, the body 21 is further provided with a controller and a communication module. The controller is communicatively connected to the communication module, the drive unit 71, and the monitoring camera 4. The controller is remotely connected to the server through the communication module. Monitoring personnel can send control signals to the controller through the server and the communication module. The controller can control components such as the drive unit 71 and the monitoring camera 4 according to the control signals, so that the habitat monitoring device 100 can automatically monitor the habitat of the power transmission line area. In addition, when the habitat monitoring device 100 determines that the stop block 76 is outside the stop groove 77, the habitat monitoring device 100 can send a component damage signal to the server. Upon receiving the component damage signal, the server can remind the monitoring personnel to replace the clutch 75 in a timely manner.

[0056] In some specific embodiments of this application, such as Figure 2 As shown, a photovoltaic panel 9 is also installed on the outer wall of the body 21. The photovoltaic panel 9 is electrically connected to the various electrical components of the habitat monitoring device 100. The photovoltaic panel 9 is used to supply power to the controller and other electrical components to ensure that the habitat monitoring device 100 can work in the field for a long time. Furthermore, a battery pack is also installed inside the body 21. The battery pack is electrically connected to the various electrical components of the habitat monitoring device 100. The battery pack is used to store electrical energy and supply power to the controller and other electrical components. The battery pack can store the electrical energy generated by the photovoltaic panel 9, thereby ensuring that the habitat monitoring device 100 can work normally in low light environments.

[0057] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
