[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0030] Reference Figure 1-Figure 7 As shown, the utility model discloses a laser ranging and positioning device for a hydrogen storage tank, comprising:

[0031] A support assembly 1 includes two vertical poles 11, a first crossbeam 12 and a second crossbeam 13 are provided between the two vertical poles 11, and the first crossbeam 12 is provided on top of the second crossbeam 13;

[0032] a detection assembly 2, the detection assembly 2 being disposed between the first crossbeam 12 and the second crossbeam 13, the detection assembly 2 comprising a guide rail 21 and a laser rangefinder 22, the guide rail 21 being disposed axially along the first crossbeam 12, the laser rangefinder 22 being slidably connected to the guide rail 21;

[0033] The sealing assembly 3 includes a sealing plate 31 and a sealing shell 32. The sealing plate 31 and the sealing shell 32 are arranged on both sides of the first beam 12 and the second beam 13, and the sealing plate 31 is attached to one end close to the emission port of the laser rangefinder 22. The sealing plate 31 has a measuring port 311 along the axial direction of the first beam 12, and the measuring port 311 corresponds to the position of the laser rangefinder 22. A first rain shield 33 is provided at the end of the measuring port 311.

[0034] It can be imagined that the present invention measures the size of the hydrogen storage tank by sliding the laser rangefinder 22 on the guide rail 21. Specifically, the guide rail 21 is installed on the crossbeam, and the installation direction of the guide rail 21 is consistent with the axial direction of the crossbeam. The laser rangefinder 22 can move the guide rail 21 left and right to measure. The sealing surface and the sealing shell 32 provided on both sides of the crossbeam are used to protect the internal laser rangefinder 22 and the guide rail 21 and seal them so that the entire detection assembly 2 can adapt to the harsh external environment and is not affected by the external weather. In order not to affect the normal operation of the laser rangefinder 22, a measuring port 311 is opened on the sealing plate 31. The measuring port 311 is a rectangular long strip hole. When the laser rangefinder 22 slides on the guide rail 21, it can emit light through the measuring port 311 to detect the hydrogen storage tank to be tested. Secondly, the first rain shield 33 provided at the measuring port 311 is used to protect the internal laser rangefinder 22, thereby preventing the entry of rainwater and sand in bad weather such as rain and dust, thereby protecting it and not affecting normal measurement.

[0035] The utility model protects the internal detection component 2 through the sealing plate 31 and the sealing shell 32, preventing normal measurement from being affected by external factors and protecting the normal use of various internal components; secondly, the first rain shield 33 arranged at the measuring port 311 can prevent the entry of rainwater and sand and stones, prevent the internal components from rusting and jamming, and extend the service life of the entire detection device.

[0036] Furthermore, the detection assembly 2 also includes a mounting plate 27 and a rack 23. The mounting plate 27 is disposed between the laser rangefinder 22 and the guide rail 21. A drive source 26 is disposed on the mounting plate 27. The rack 23 is axially disposed on the first crossbeam 12 along the first crossbeam 12. A gear 25 meshing with the rack 23 is disposed at the output end of the drive source 26. The mounting plate 27 is slidably connected to the guide rail 21 via a slider.

[0037] Specifically, the mounting plate 27 is slidably connected to the guide rail 21 via a slider, and the drive source 26 is then mounted on the mounting plate 27, driving the drive source 26 to move linearly along the guide rail 21. A rack 23 is mounted on the first crossbeam 12, parallel to the guide rail 21, and oriented in a direction to effectively prevent rainwater and wind-blown sand from penetrating, extending the service life of the mechanism. A gear 25 is mounted on the output end of the drive source 26, meshing with the rack 23 to convert the circular motion of the output end of the drive source 26 into linear motion.

[0038] As a preferred solution of the present invention, due to the particularity of the on-site working environment, it is necessary to avoid the generation of electric sparks. The driving source 26 in the present invention is an explosion-proof servo motor, and copper wire grounding is adopted (such as using screws to lock the parts or any part is connected to the power, the two are connected by a copper wire for grounding, and the whole is also grounded by a copper wire) to ensure that it can be applied in the hydrogen exchange environment.

[0039] Furthermore, first photoelectric sensors 28 are respectively provided at both ends of the first beam 12 , and the photoelectric sensors are electrically connected to the driving source 26 .

[0040] Specifically, two photoelectric sensors are provided at both ends of the guide rail 21 to limit the rotation of the drive source 26 and prevent the drive source 26 from colliding with the machine. During use, the photoelectric sensor detects the drive source 26 in position signal and feeds the signal back to the drive source 26 to limit the operation of the drive source 26.

[0041] Furthermore, an outer cover of the laser rangefinder 22 is provided with an explosion-proof box 221 , and the explosion-proof box 221 is connected to the mounting plate 27 .

[0042] Specifically, the explosion-proof box 221 can be used safely in hazardous environments. Its essence is to prevent explosions and fire accidents. The explosion-proof box 221 generally has strict explosion-proof performance. The working state and position relationship of its internal devices will not cause sparks or high temperatures that could cause explosions, thereby ensuring a safe working environment.

[0043] In addition, due to the particularity of the environment in which the device of the present invention is located, explosion-proof measures are required. Specifically, as a preferred solution of the present invention, the materials of the guide rail 21, gear 23 and rack 25 are all explosion-proof materials.

[0044] Specifically, limit plates 211 are provided at both ends of the guide rail 21. The limit plates 211 are clamped on both sides of the guide rail 21 and connected to the first crossbeam 12. They are used to hard limit the movement of the driving source 26 to avoid errors in the photoelectric signal and the occurrence of collision accidents.

[0045] Furthermore, a second photoelectric sensor 29 is provided on the first crossbeam 12. The second photoelectric sensor 29 is disposed opposite the sealing plate 31. The sealing plate 31 has a detection port 312 corresponding to the position of the second photoelectric sensor 29. Specifically, the second photoelectric sensor 29 is used to detect the position information of the vehicle ahead and identify the vehicle's position.

[0046] Furthermore, a second rain shield 34 is provided at the end of the detection port 312 , and both the first rain shield 33 and the second rain shield 34 are provided with a slope.

[0047] Specifically, like the measurement port 311, the detection port 312 is provided to facilitate the operation of the second photoelectric sensor 29. Similarly, the second rain shield 34 is provided at the detection port 312 to prevent the ingress of rainwater and sand and stone from affecting its use. Furthermore, the first and second rain shields 33, 34 are sloped to divert rainwater.

[0048] Furthermore, in order to improve the protective effect of the first rain shield 33 and the second rain shield 34 , the size of the first rain shield 33 is larger than the size of the measuring port 311 , and the size of the second rain shield 34 is larger than the size of the detection port 312 .

[0049] Furthermore, a reinforcing rib 14 is provided between the second cross beam 13 and the vertical pole 11. An anchor plate 15 is provided at the bottom of the vertical pole 11, and a chemical bolt 16 is passed through the anchor plate 15.

[0050] Specifically, the provision of the reinforcing ribs 14 can improve the stability of the entire support assembly 1, thereby ensuring the accuracy of the test results; the chemical bolts 16 are used to fix the uprights 11 to the base plate, and have good stability after connection.

[0051] In summary, the utility model introduces a laser ranging and positioning device for a hydrogen storage tank. The utility model protects the internal detection component 2 through a sealing plate 31 and a sealing shell 32 to prevent normal measurement from being affected by external factors and to protect the normal use of various internal components; secondly, the first rain shield 33 arranged at the measuring port 311 can prevent the entry of rainwater and sand and stones, prevent the rust and jamming of internal components, and extend the service life of the entire detection device.

[0052] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
