Description

Technical Field

[0001] This application relates to the field of dust covers, and more particularly to a laser scanning dust cover. Background Technology

[0002] Currently, laser scanning utilizes lasers to scan the surrounding environment (collecting data) to meet specific application needs, providing functions such as presence / absence detection, anomaly detection, and location determination. It can be widely applied in outdoor equipment, bulk cargo terminals, container terminals, steel mills, mines, AGV vehicles, and other locations and scenarios. Laser scanning technology is suitable for two-dimensional line scanning lasers with cylindrical or conical lenses.

[0003] When laser scanners operate outdoors or in harsh environments, the laser detection mask can become covered in dust or worn down by sandstorms, reducing its light transmittance and leading to shorter detection distances or misreadings; this also increases the frequency of maintenance. Furthermore, prolonged outdoor exposure can cause laser scanners to age and experience reduced sealing performance. Utility Model Content

[0004] To reduce wind and sand erosion, this application provides a laser scanning dust cover.

[0005] This application provides a laser scanning dust cover with the following technical solution: A laser scanning dust cover includes a push rod seat disposed on the outside of a laser scanner above a mounting base. An electric push rod is provided on one side of the push rod seat, and the output end of the electric push rod is connected to the dust cover. A first dustproof cotton is provided on the bottom surface of the dust cover, located at the right connection point between the dust cover and the push rod seat. A second dustproof cotton is provided on the surface of the dust cover, located at the left connection point between the dust cover and the push rod seat. A third dustproof cotton is provided inside the push rod seat, located at the connection point between the push rod seat and the laser scanner.

[0006] By adopting the above technical solution, when the laser scanner is needed, the electric push rod will be activated to raise the dust cover, thus exposing the laser scanner for laser scanning. After use, the electric push rod will be activated to lower the dust cover to cover the laser scanner, providing protection for the scanning head and preventing external wind and sand from damaging it. The first and second dustproof cotton will fill the gaps at the connection between the dust cover and the push rod seat, and the third dustproof cotton will fill the gaps at the connection between the push rod seat and the laser scanner, preventing wind and sand from seeping in and improving the protection effect.

[0007] Preferably, the top of the push rod seat is provided with an annular groove for engaging the second dustproof cotton.

[0008] By adopting the above technical solution, an annular groove is provided at the top of the push rod seat. The annular groove matches the size of the second dustproof cotton, thus facilitating the assembly of the second dustproof cotton onto the push rod seat.

[0009] In summary, this application includes at least one of the following beneficial technical effects:

[0010] 1. Activate the electric push rod. The electric push rod will raise the dust cover, thereby exposing the laser scanner for laser scanning. After use, the electric push rod will activate again to lower the dust cover to cover the laser scanner, providing protection for the scanner head and preventing external wind and sand from damaging it. The first and second dustproof cotton will fill the gaps between the dust cover and the push rod base, and the third dustproof cotton will fill the gaps between the push rod base and the laser scanner, preventing wind and sand from seeping in and improving the protection effect.

[0011] 2. By providing an annular groove at the top of the push rod seat, which matches the size of the second dustproof cotton, it is convenient to assemble the second dustproof cotton onto the push rod seat; in addition, by adopting a special design for the electric push rod, the electric push rod has an IP67 protection rating, which can improve the service life of the electric push rod and enable it to be used effectively outdoors.

[0017] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0018] This application discloses a laser scanning dust cover.

[0019] Reference Figures 1-3A laser scanner dust cover includes a push rod base 3 located on the outside of a laser scanner 2 mounted on a mounting base 1. The laser scanner 2 collects environmental data. The push rod base 3 provides support and fixation for an electric push rod 4. An electric push rod 4 is located on one side of the push rod base 3. The output end of the electric push rod 4 is connected to a dust cover 5, which provides power to the dust cover 5. The electric push rod 4 is connected to an external PLC, and its signal is controlled by the external PLC program to ensure the lifting and lowering of the dust cover 5. The dust cover 5 protects the laser scanner 2. A first dustproof cotton 6 is located on the bottom surface of the dust cover 5 at the right connection point between the dust cover 5 and the push rod base 3. A second dustproof cotton 7 is located on the surface of the dust cover 5 at the left connection point between the dust cover 5 and the push rod base 3. The first and second dustproof cotton 6 fill the connection between the dust cover 5 and the push rod base 3. At the joint, to ensure the airtightness of the connection gap when the dust cover 5 protects the laser scanner 2, a third dustproof cotton 8 is provided inside the push rod seat 3. The third dustproof cotton 8 is located at the connection between the push rod seat 3 and the laser scanner 2. The third dustproof cotton 8 will fill the gap at the connection between the push rod seat 3 and the laser scanner 2 to prevent wind and sand from seeping in. When the laser scanner 2 needs to be used, the electric push rod 4 will start to drive the dust cover 5 to rise, thus exposing the laser scanner 2 for laser scanning. After use, the electric push rod 4 will start to drive the dust cover 5 to fall and cover the laser scanner 2, providing protection for the scanning head of the laser scanner 2 and preventing external wind and sand from damaging the scanning head of the laser scanner 2. The first dustproof cotton 6 and the second dustproof cotton 7 fill the gap at the connection between the dust cover 5 and the push rod seat 3, and the third dustproof cotton 8 fills the gap at the connection between the push rod seat 3 and the laser scanner 2, preventing wind and sand from seeping in and improving the protection effect.

[0020] Reference Figures 2-4 The top of the push rod seat 3 is provided with an annular groove for engaging the second dustproof cotton 7.

[0021] Specifically, by providing an annular groove at the top of the push rod seat 3, and the annular groove at the top of the push rod seat 3 matching the size of the second dustproof cotton 7, it is convenient to assemble the second dustproof cotton 7 onto the push rod seat 3.

[0022] The implementation principle of a laser scanner dust cover in this application embodiment is as follows: When the laser scanner 2 needs to be used, the electric push rod 4 will start and drive the dust cover 5 to rise, thus exposing the laser scanner 2 for laser scanning. After use, the electric push rod 4 will start and drive the dust cover 5 to fall and cover the laser scanner 2, providing protection for the scanning head of the laser scanner 2 and preventing external wind and sand from damaging the scanning head of the laser scanner 2. The first dustproof cotton 6 and the second dustproof cotton 7 will fill the gap at the connection between the dust cover 5 and the push rod seat 3, and the third dustproof cotton 8 will fill the gap at the connection between the push rod seat 3 and the laser scanner 2, preventing wind and sand from seeping in from the gaps and improving the protection effect.

[0023] In addition, the dust cover 5 of this application can shield and protect the scanning head of the laser scanner 2, thereby slowing down the aging of plastic components and increasing the service life of the laser scanner 2.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
