[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In the description of the embodiments of the present application, it should be noted that the terms "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0031] The present application embodiment provides an inertia emergency brake device, such as Figures 1 to 3 The inertia emergency brake device comprises a first mounting member 100 , a second mounting member 200 , a rotating wheel 300 , an inertia assembly 400 , a clamping plate 500 , a shoe block 600 and a transmission assembly 700 .

[0032] The first mounting member 100 and the second mounting member 200 are used to be mounted on the photovoltaic panel transportation device. Specifically, the first mounting member 100 and the second mounting member 200 can be two components or an integrated structure.

[0033] The rotating wheel 300 is rotatably mounted on the first mounting member 100, and is used to be close to the cable and rotate on the cable. The rotating wheel 300 is close to the cable, and when the photovoltaic transport device moves on the cable, the rotating wheel 300 rotates, and the rotation speed of the rotating wheel 300 matches the moving speed of the photovoltaic transport device on the cable.

[0034] Reference Figure 1 and Figure 2 The inertial assembly 400 includes a housing 410, a spring 430 and a slider 420. The housing 410 is mounted on the end surface of the rotating wheel 300 and defines a slide groove 411. The two ends of the spring 430 are respectively connected to the slider 420 and the housing 410; the slider 420 is slidably mounted in the slide groove 411 and is configured to overcome the elastic force of the spring 430 and slide out of the opening of the slide groove 411 when the rotation speed of the housing 410 exceeds a preset rotation speed.

[0035] For example, Figure 2 The inertial assembly 400 shown in the figure includes two sliders 420 and two springs 430. The housing 410 defines two slide slots 411. The two sliders 420 are respectively installed in the two slide slots 411. One end of the two springs 430 is respectively connected to the two sliders 420, and the other end of the two springs 430 is connected to the housing 410. Of course, the sliders 420 and the springs 430 of the inertial assembly 400 can also be one, three, four or other numbers.

[0036] The spring 430 provides centripetal force for the slider 420. When the photovoltaic panel transport device slides on the cable uncontrollably, the rotation speed of the rotating wheel 300 increases rapidly, and the rotation speed of the inertial component 400 also increases rapidly along with the rotating wheel 300, causing the spring 430 to be unable to provide sufficient centripetal force, causing the slider 420 to quickly slide out of the opening of the slide groove 411 and drive the transmission component 700.

[0037] The clamping plate 500 is disposed on the second mounting member 200, and the shoe-shaped block 600 is rotatably connected to the second mounting member 200 and is spaced apart from the clamping plate 500 to define a cable channel 610 for the cable to pass through. When the photovoltaic panel transport device moves normally on the cable, the cable passes through the cable channel 610, and there is a gap between the outer side of the cable and the shoe-shaped block 600.

[0038] The transmission assembly 700 is connected to the shoe block 600 and is configured to be driven by the slider 420 that slides out of the slide slot 411 and drives the shoe block 600 to rotate so as to press the cables in the cable channel 610 toward the clamping plate 500 .

[0039] When the photovoltaic panel transport device slides uncontrollably on the cable due to power failure or failure, the photovoltaic panel transport device slides quickly on the cable, the rotation speed of the rotating wheel 300 increases, the inertial assembly 400 connected to the rotating wheel 300 rotates quickly with the rotating wheel 300, the slider 420 slides out from the opening of the slide slot 411, and the slider 420 drives the transmission assembly 700, so that the transmission assembly 700 drives the boot block 600 to rotate, and the boot block 600 presses the cable in the cable channel 610, and the cable is clamped by the clamping plate 500 and the boot block 600 to achieve braking. Therefore, the inertial emergency braking device provided in the embodiment of the present application can use inertia to brake the photovoltaic transport device when the photovoltaic panel transport device slides uncontrollably on the cable, thereby avoiding damage and safety hazards caused by the uncontrolled sliding of the photovoltaic panel transport device.

[0040] Continue to refer to Figures 1 to 3 In some embodiments of the present application, the transmission assembly 700 includes a first swing arm 710, a second swing arm 720, a guide member 730 and a guide bracket 740. One end of the first swing arm 710 is rotatably connected to the first mounting member 100, and the other end of the first swing arm 710 is rotatably connected to one end of the second swing arm 720 and is close to the inertial assembly 400. The end of the second swing arm 720 away from the first swing arm 710 abuts against the top of the boot block 600. One end of the guide member 730 is slidably connected to the guide bracket 740, and the other end of the guide member 730 is connected to the end of the second swing arm 720 away from the first swing arm 710, and is configured to limit the second swing arm 720 to move along the extension direction of the cable.

[0041] The contact point between the second swing arm 720 and the shoe-shaped block 600 is located on the side of the rotation axis of the shoe-shaped block 600 close to the inertial assembly 400. When the slider 420 slides out of the slide slot 411, the slider 420 hits the end of the first swing arm 710 connected to the second swing arm 720, and the second swing arm 720 moves away from the inertial assembly 400. The contact point between the second swing arm 720 and the shoe-shaped block 600 approaches the rotation axis of the shoe-shaped block 600, and then the end of the second swing arm 720 away from the first swing arm 710 drives the shoe-shaped block 600 to rotate. Specifically, the shoe-shaped block 600 moves along Figure 3 The first direction of rotation is shown.

[0042] Exemplarily, the guide bracket 740 is disposed on the first mounting member 100. Of course, the guide bracket 740 may also be disposed on the second mounting member 200, or on the photovoltaic transport device.

[0043] Furthermore, the transmission assembly 700 further includes an impact block 750. The impact block 750 is disposed at the end of the first swing arm 710 connected to the second swing arm 720, or the impact block 750 is disposed at the end of the second swing arm 720 connected to the first swing arm 710. The impact block 750 is used to withstand the impact of the slider 420. When the impact block 750 is impacted, the first swing arm 710 is driven to rotate and the second swing arm 720 is driven to move in a direction away from the inertial assembly 400.

[0044] In addition, the transmission assembly 700 further includes a driving wheel 760 . The driving wheel 760 is rotatably connected to the end of the second swing arm 720 away from the first swing arm 710 , and abuts against the top of the shoe-shaped block 600 .

[0045] The transmission assembly 700 is not limited to the above structure. In other embodiments of the present application, the transmission assembly 700 may also be in other structural forms.

[0046] In some embodiments of the present application, the inertia emergency brake device further includes a limit cover 800. The limit cover 800 is connected to the clamping plate 500 and covers the clamping plate 500, and a through hole 810 is provided on the top surface of the limit cover 800 for the shoe block 600 to pass through and move.

[0047] The limiting cover 800 can ensure that the cable will not be separated from the boot-shaped block 600 and the clamping plate 500 when the cable is clamped, thereby improving the reliability of the inertial emergency braking device in braking the photovoltaic panel transport device.

[0048] Specifically, the clamping plate 500 is defined with a semicircular portion 510 adapted to the cable, the semicircular portion 510 protrudes in a direction away from the shoe-shaped block 600, and a cable channel 610 is formed between the semicircular portion 510 and the shoe-shaped block 600. The semicircular portion 510 can semi-enclose the cable, further preventing the cable from being separated from between the shoe-shaped block 600 and the clamping plate 500.

[0049] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0050] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
