Exemplary embodiments will be described in detail here, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] A fall protection device for sensors, comprising:

[0028] The mounting cover 1 is configured to fix the sensor 5;

[0029] A housing, located outside the mounting cover 1, is configured to protect the sensor 5;

[0030] An elastic rope 3 is provided between the fixing cover 1 and the housing. The two ends of the elastic rope 3 are respectively connected to the outer surface of the fixing cover 1 and the inner surface of the housing. The housing is also provided with a wire hole 4, which is configured to accommodate the connecting wire 6 of the sensor 5. The housing has a spherical structure so that the housing completely covers the sensor 5.

[0031] In this embodiment, by setting up a multi-layered sleeve structure of fixing cover 1, housing and elastic rope 3, the sensor 5 can be suspended and fixed inside the housing. The spherical structure can reduce the overall wear and damage during the dragging of the sensor 5 connecting line 6, and at the same time avoid the sensor 5 from contacting the tower structure to cause friction damage, ensuring that even if it falls and bumps, the sensor 5 will not be violently impacted, thus playing a better protective role.

[0032] This application may further include the following technical solution: the housing includes a spherical inner housing and a spherical outer housing, the inner housing being smaller than the outer housing, and the centers of the inner housing and the outer housing being at the same position. Multiple shock-absorbing springs 2 are also provided between the inner housing and the outer housing. The shock-absorbing springs 2 can further improve the structural stability of the housing, reduce damage to the housing caused by collisions, or reduce the transmission of collision force to the internal sensors 5.

[0033] The present application may further include the following technical solution: multiple shock absorber springs 2 are arranged in a ring on the spherical structure, and the overall structural stability is improved by the ring arrangement. The multiple shock absorber springs 2 within each ring arrangement range are equally spaced, so as to disperse the force on the shell by the uniformly distributed shock absorber springs 2, thereby improving the uniformity of the force on the shell and the structural stability.

[0034] This application may further include the following technical solution: the housing includes a hemispherical front housing 7 and a hemispherical rear housing 8, the connection position of the front housing 7 and the rear housing 8 forming an annular clearance window 10, the central axis of the clearance window 10 coinciding with the central axis of the wire hole 4. By setting the coinciding central axis, the possibility of misalignment and bending between the connecting wire 6 and the sensor 5 can be reduced, thereby extending the service life of the connecting wire 6.

[0035] The application may further include the following technical solution: the front housing 7 is provided with a locking protrusion at the clearance window 10, and the rear housing 8 is provided with a locking recess at the clearance window 10. The locking protrusion and the locking recess are connected to each other so that the front housing 7 and the rear housing 8 form a closed sphere after being connected.

[0036] Optionally, the front housing 7 and the rear housing 8 are respectively provided with external threads and internal threads near the relief window 10. When the external threads and internal threads are connected, the front housing 7 and the rear housing 8 are connected to form a closed sphere.

[0037] This application may further include the following technical solution: two wire holes 4 are provided, and the two wire holes 4 are located on the same central axis of the housing, so as to improve the connection stability between the connecting wire 6 and the sensor 5, reduce the damage caused by bending, and extend its service life.

[0038] This application may further include the following technical solution: a rubber pad layer 9 is provided on the inner wall of the wire hole 4 to reduce frictional damage between the connecting wire 6 and the wire hole 4, extend the service life of the connecting wire 6, and the rubber pad layer 9 can also prevent signal transmission instability caused by damage to the connecting wire 6.

[0039] The present application may further include the following technical solution: the fixing cover 1 is also provided with a connector, which is fixedly connected to the sensor 5. Optionally, the connector is a snap-fit, which facilitates quick snap-fit ​​of the sensor 5.

[0040] This application may further include the following technical solution: a rubber pad layer 9 is provided on the inner wall of the fixing cover 1, thereby using the rubber pad layer 9 to enhance the stability of the connection between the sensor 5 and the fixing cover 1.

[0041] The application may further include the following technical solution: the fixing cover 1 includes an elastic sleeve, which is configured to fit and fix sensors 5 of different sizes, thereby using the fitting method to quickly fix sensors 5 of different sizes and improve the universality of the protection device.

[0042] In use, the front housing 7 and rear housing 8 are opened, and the sensor 5 is installed into the fixed cover 1 through the clearance window 10. The connecting wires 6 at both ends of the sensor 5 are passed through the wire holes 4 on both sides, and then the front housing 7 and rear housing 8 are connected to form a spherical protective structure. During operation, when the sensor 5 falls from a height, the outer housing will hit the ground first. The internal shock-absorbing spring 2 will absorb the impact force from the ground. The sensor 5 inside the fixed cover 1 will shake due to inertia. The reaction force brought by the internally connected elastic rope 3 will reduce the shaking amplitude of the fixed cover 1, thereby reducing the shaking amplitude of the sensor 5 and keeping it stable, thus protecting the sensor 5 and offsetting the damage from external impacts. Moreover, only one person is needed to quickly complete the installation and adjustment of the sensor 5 protection device, effectively improving work efficiency. The quick connection and elastic structure design of the protection device ensure the safety and reliability of the entire protection device during use.
