Description

Technical Field

[0001] This invention relates to the field of hydrogen power generation equipment technology, and in particular to a safety monitoring device for hydrogen power generation equipment. Background Technology

[0002] Hydrogen-powered vehicles typically consist of a hydrogen fuel cell power generation system, a hydrogen storage system, an energy storage system, an uninterruptible power supply system, a control system, a monitoring system, and a chassis. Because hydrogen is a flammable and explosive gas, improper safety measures during its use can easily lead to fires and explosions, causing casualties and property damage. Therefore, monitoring the overall condition of a hydrogen-powered vehicle is crucial. During operation, the monitoring system can monitor the real-time operating status of each module system and the environmental conditions to ensure the safe and stable operation of the vehicle.

[0003] In actual use, since most of the power distribution equipment is installed outdoors by the roadside, hydrogen fuel cell vehicles are mostly parked and working on the roadside. The display panel of the monitoring system inevitably encounters situations such as sewage splashing, dust, and floating particles falling on the display panel. Therefore, operators need to manually clean the display panel after use, which is time-consuming and laborious, reducing the efficiency of hydrogen fuel cell vehicles. Summary of the Invention

[0019] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The following is for reference. Figures 1-11 A safety monitoring device 1000 for hydrogen power generation equipment according to an embodiment of the present invention is described.

[0021] like Figure 1 As shown, a safety monitoring device 1000 for hydrogen power generation equipment according to an embodiment of the present invention includes: a hydrogen power generation device 400, a cover plate 200, and a cleaning component 100. The hydrogen power generation device 400 includes: a housing 410 and a monitoring system 420, the housing 410 being positioned in a first direction (e.g.,...). Figure 2 A mounting slot 411 is provided on one side (shown in the left-right direction). The monitoring system 420 includes a display panel 421, which is installed in the mounting slot 411. A cover plate 200 is installed on the housing 410 and can be opened to cover the opening of the mounting slot 411. A cleaning component 100 is provided in the mounting slot 411. The cleaning component 100 includes a winding mechanism 10 and a cleaning mechanism 20. The cover plate 200 is configured to drive the cleaning mechanism 20 in a second direction (e.g., left-right direction) when opened. Figure 2 The cleaning mechanism 20 moves in the up-down direction (as shown) to clean the display panel 421. The winding mechanism 10 is configured to drive the cleaning mechanism 20 to move in a second direction to clean the display panel 421 when the cover 200 is closed. The second direction intersects with the first direction.

[0022] In this embodiment, the hydrogen power generation equipment safety monitoring device 1000 includes a hydrogen power generation equipment 400, a cover plate 200, and a cleaning component 100. The hydrogen power generation equipment 400 is equipped with a housing 410 and a monitoring system 420. For example, the housing 410 can be equipped with a hydrogen power generation system, a hydrogen storage system, and other devices, as well as pipelines and other transportation structures, to meet the operational needs of the hydrogen power generation equipment 400.

[0023] The housing 410 has a mounting groove 411 on one side in the first direction. A cover plate 200 is detachably provided over the opening of the mounting groove 411. A display panel 421 is installed in the mounting groove 411. For example, the display panel 421 can be installed on the bottom wall of the mounting groove 411 in the first direction. During the use of the hydrogen power generation equipment 400, the operator can open the cover plate 200 to view the information on the display panel 421. After the hydrogen power generation equipment 400 is used, the operator can close the cover plate 200, thereby enclosing the display panel 421 in the mounting groove 411, so that the cover plate 200 can protect the display panel 421.

[0024] This embodiment also includes a cleaning component 100, which is disposed within the mounting slot 411 and includes a winding mechanism 10 and a cleaning mechanism 20. The cover plate 200 is configured to drive the cleaning mechanism 20 to move along a second direction to clean the display panel 421 when it is open. The winding mechanism 10 is configured to drive the cleaning mechanism 20 to clean the display panel 421 along the second direction when the cover plate 200 is closed. For example, when the cover plate 200 is closed, the cleaning mechanism 20 can be located on one side of the display panel 421 in the second direction. During the opening process of the cover plate 200, the cover plate 200 can drive the cleaning mechanism 20 to move from one side of the display panel 421 to the other side, thereby cleaning the display panel 421. After the cleaning mechanism 20 moves from one side of the display panel 421 to the other, the cleaning mechanism 20 completes the cleaning of the display panel 421, and the operator can view and use the display panel 421 normally. After the hydrogen power generation equipment 400 is used, as the cover 200 is closed, the winding mechanism 10 drives the cleaning mechanism 20 to move from the other side of the display panel 421 to one side, thereby cleaning the display panel 421 again. This effectively removes dirt such as floating dust and sewage accumulated on the display panel 421 during the use of the hydrogen power generation equipment 400, and allows the cleaning mechanism 20 to return to its initial position, so that the cleaning mechanism 20 can continue to clean the display panel 421 when the hydrogen power generation equipment 400 is used again.

[0025] In this embodiment, when the cover plate 200 is opened, the cleaning mechanism 20 is driven to move and clean the display panel 421. When the cover plate 200 is closed, the winding mechanism 10 drives the cleaning mechanism 20 to move and reset and clean the display panel 421 again. This allows the display panel 421 to achieve a good cleaning effect. Furthermore, during the use of the hydrogen power generation equipment 400, the operator can complete the cleaning of the display panel 421 while opening and closing the cover plate 200, which greatly saves the manpower and time spent on manual cleaning. It can achieve a certain degree of imperceptible cleaning effect, making the cleaning of the display panel 421 more time-saving and convenient, and making the use of the hydrogen power generation equipment 400 more convenient and efficient.

[0026] In this embodiment, the second direction intersects with the first direction, which is intended to illustrate that the first direction and the second direction can be arranged perpendicularly or they can be arranged in a non-perpendicular manner that only intersects.

[0027] According to an embodiment of the present invention, a safety monitoring device 1000 for hydrogen power generation equipment includes a cleaning component 100, comprising a cleaning mechanism 20 and a winding mechanism 10. The cover plate 200 is configured to drive the cleaning mechanism 20 to move along a second direction to clean the display panel 421 when the cover plate 200 is open, and the winding mechanism 10 is configured to drive the cleaning mechanism 20 to move along the second direction to clean the display panel 421 when the cover plate 200 is closed. This allows the operator to clean the display panel 421 while opening and closing the cover plate 200 during the use of the hydrogen power generation equipment 400, effectively saving manpower and time costs associated with manual cleaning. This makes cleaning the display panel 421 more time-saving and convenient, and makes the use of the hydrogen power generation equipment 400 more convenient and efficient.

[0028] In some embodiments of the present invention, such as Figure 3 and Figure 5 As shown, the cover plate 200 has a first end and a second end at its two ends in the second direction, respectively. The first end is rotatably connected to the housing 410, and the axis of rotation of the first end is along a third direction (e.g., Figure 5 Extending in the forward and backward directions shown, the third direction intersects the second and first directions in pairs. The winding mechanism 10 may include: a first traction rope 13, a winding drum 11, a spiral spring 12, a second traction rope 14, and a guide block 15.

[0029] Specifically, one end of the first traction rope 13 is connected to the cleaning mechanism 20; the take-up drum 11 extends along a third direction and is rotatably disposed in the mounting groove 411; one end of the spiral spring 12 is connected to the take-up drum 11, and the other end of the spiral spring 12 is connected to the inner wall of the mounting groove 411. In the second direction, the take-up drum 11 and the first end are located on the same side of the display panel 421 in the second direction; the other end of the first traction rope 13 is wound around the take-up drum 11; one end of the second traction rope 14 is connected to the cleaning assembly 100, and the second traction rope 14... The other end is connected to the second end of the cover plate 200, which is configured to drive the cleaning mechanism 20 away from the winding drum 11 by the second traction rope 14 when opened; the guide block 15 is provided on the other side of the display panel 421 in the second direction, the guide block 15 is provided with a guide groove 151, and the second traction rope 14 passes through the guide groove 151, wherein the guide groove 151 forms a first opening on the side surface of the guide block 15 facing the display panel 421, and in the first direction, the guide groove 151 forms a second opening on the side surface of the guide block 15 facing the cover plate 200.

[0030] In this embodiment, the cover plate 200 has a first end and a second end at its two ends in the second direction, respectively. The first end is rotatably connected to the housing 410. For example, the cover plate 200 can be hinged to the housing 410 at the first end. For example, the periphery of the opening of the mounting groove 411 can form a sealing groove that cooperates with the cover plate 200. When the cover plate 200 is in the closed state, the outer surface of the cover plate 200 in the first direction can be flush with the surface of the housing 410, so that the cover plate 200 can stably close the mounting groove 411.

[0031] If the rotation axis of the first end extends along a third direction, then when the cover plate 200 is opened, the second end of the cover plate 200 moves away from the opening of the mounting groove 411 along the first and second directions around the rotation axis of the first end. For example, after the cover plate 200 is fully opened, the second end of the cover plate 200 can be located on the side of the first end away from the mounting groove 411 in the second direction, so that the display panel 421 can be fully exposed to the opening of the mounting groove 411. This can effectively reduce the obstruction of the display panel 421 by the cover plate 200, and make it convenient for the operator to view and use the display panel 421.

[0032] In this embodiment, the third direction intersects with both the second and first directions, which is intended to illustrate that the first and second directions can be arranged perpendicularly or only intersecting without being perpendicular. The first direction and the third direction can be arranged perpendicularly or only intersecting without being perpendicular. The second direction and the third direction can be arranged perpendicularly or only intersecting without being perpendicular.

[0033] In this embodiment, the first ends of the winding drum 11 and the cover plate 200 are located on the same side of the display panel 421 in the second direction. The winding drum 11 is rotatably disposed in the mounting groove 411. One end of the spiral spring 12 is connected to the winding drum 11 and the other end is connected to the inner wall of the mounting groove 411. The spiral spring 12 plays a role in resetting the winding drum 11, so that after the winding drum 11 rotates a certain angle under the action of external force, when the external force disappears, the winding drum 11 can reverse and rotate under the action of the spiral spring 12. At the same angle, one end of the first traction rope 13 is connected to the cleaning mechanism 20, and the other end of the first traction rope 13 is wound around the take-up drum 11. When the cleaning mechanism 20 moves away from the take-up drum 11 in the second direction, the first traction rope 13 unfolds in the second direction and drives the take-up drum 11 to rotate. When the cleaning mechanism 20 moves closer to the take-up drum 11 in the second direction, the take-up drum 11 can reverse under the action of the spiral spring 12 and wind the first traction rope 13, so that the first traction rope 13 is wound onto the take-up drum 11.

[0034] One end of the second traction rope 14 is connected to the cleaning assembly 100 and the other end is connected to the second end of the cover plate 200. The cover plate 200 is configured to drive the cleaning mechanism 20 away from the winding drum 11 via the second traction rope 14 when it is open. For example, when the cover plate 200 is closed, the cleaning mechanism 20 can be located on the same side of the display panel 421 in the second direction as the winding drum 11 and the first end are located. When the cover plate 200 is open, the second traction rope 14 drives the cleaning mechanism 20 to move from one side of the display panel 421 to the other side as the second end moves.

[0035] In this embodiment, the guide block 15 is disposed on the other side of the display panel 421 in the second direction. The guide block 15 is provided with a guide groove 151, which has a first opening and a second opening. The first opening faces the display panel 421 in the second direction, and the second opening faces the cover plate 200 in the first direction. For example, the guide groove 151 can be formed as an L-shaped groove, and the inner wall of the guide groove 151 can be an arc surface at the corner. The second traction rope 14 passes through the guide groove 151. During the opening of the cover plate 200, the second traction rope 14 is positioned between the cleaning mechanism 20 and the guide block under the guiding and limiting action of the guide groove 151. The portion between 15 can move stably along the second direction, thereby allowing the cleaning mechanism 20 to move stably along the second direction from one side of the display panel 421 to the other side for cleaning. When the cover plate 200 is closed, the force applied to the cleaning mechanism 20 by the cover plate 200 through the second traction rope 14 gradually decreases, allowing the winding drum 11 and the spiral spring 12 to stably drive the cleaning mechanism 20 along the second direction from one side of the display panel 421 to one side for cleaning through the first traction rope 13. This allows the cleaning mechanism 20 to clean the display panel 421 stably, reliably, and effectively.

[0036] In some examples of the present invention, references Figure 4 and Figure 7 As shown, the second direction is the up and down direction. The upper side wall of the mounting groove 411 can be formed with a storage groove 403, and the winding drum 11 and the spiral spring 12 can be set in the storage groove 403.

[0037] In this embodiment, the winding drum 11 and the spiral spring 12 are disposed in the storage groove 403. For example, the winding mechanism 10 may also include a housing, which is fixed in the storage groove 403 with its opening facing downward. The winding drum 11 and the spiral spring 12 may be arranged in the housing, and the other end of the spiral spring 12 may be connected to the inner wall of the housing. This facilitates the installation and arrangement of the winding drum 11 and the spiral spring 12.

[0038] In one embodiment of the present invention, reference is made to... Figure 4 , Figure 5 and Figure 7As shown, the second direction is the vertical direction. The take-up drum 11 is located on the upper side of the display panel 421. The cleaning mechanism 20 may include: a sliding frame 211, a cleaning cotton 213, and a water storage device 212. The sliding frame 211 extends along the third direction. In the second direction, one end of the first traction rope 13 is connected to the side of the sliding frame 211 facing the take-up drum 11, and one end of the second traction rope 14 is connected to the side of the sliding frame 211 away from the take-up drum 11. The cleaning cotton 213 is located on the sliding frame 211 and is adapted to contact the display panel 421 to clean the display panel 421. The water storage device 212 is located on the sliding frame 211 and is located on the side of the cleaning cotton 213 away from the display panel 421 in the first direction. The water storage device 212 is used to deliver cleaning fluid to the cleaning cotton 213.

[0039] In this embodiment, the second direction is the up-down direction. The winding drum 11 is located on the upper side of the display panel 421. When the cover plate 200 is in the closed state, the cleaning mechanism 20 is located on the upper side of the display panel 421. When the cover plate 200 is in the open state, the cleaning mechanism 20 is located on the lower side of the display panel 421. When the cover plate 200 is open, the cleaning mechanism 20 cleans the display panel 421 from top to bottom. When the cover plate 200 is closed, the cleaning mechanism 20 cleans the display panel 421 from bottom to top.

[0040] In this embodiment, the cleaning mechanism 20 includes a sliding frame 211, a cleaning cotton 213, and a water storage component 212. The sliding frame 211 extends in a third direction. The first traction rope 13 and the second traction rope 14 are respectively connected to the sliding frame 211. Specifically, the first traction rope 13 can be connected to the upper surface of the sliding frame 211, and the second traction rope 14 is connected to the lower surface of the sliding frame 211.

[0041] In this embodiment, the cleaning cotton 213 and the water storage component 212 are both mounted on the sliding frame 211. For example, the sliding frame 211 can form a receiving space that extends along the first direction. The cleaning cotton 213 and the water storage component 212 are installed in the receiving space. The sliding frame 211 facilitates the installation and arrangement of the cleaning cotton 213 and the water storage component 212, and facilitates the connection and fixation with the first traction rope 13 and the second traction rope 14, so that the cleaning mechanism 20 can move stably along the second direction under the pulling action of the first traction rope 13 and the second traction rope 14.

[0042] In this embodiment, the cleaning cotton 213 is adapted to contact the display panel 421 to clean the display panel 421. The water storage component 212 is located on the side of the cleaning cotton 213 away from the cleaning cotton 213 in the first direction and delivers cleaning liquid to the cleaning cotton 213. The structure is simple and the arrangement is reasonable, which can enable the cleaning cotton 213 to work with the cleaning liquid to achieve a better cleaning effect on the display panel 421 when cleaning the display panel 421.

[0043] In some examples of the present invention, such as Figure 7 and Figure 8 As shown, the water storage component 212 has a water outlet 2121 formed on the side facing the cleaning cotton 213 in the first direction. The cleaning mechanism 20 may also include: a water blocking component 214, a guide seat 216 and a first elastic component 221.

[0044] Specifically, the water-blocking member 214 extends along a third direction. In the first direction, the water-blocking member 214 is located between the water storage member 212 and the cleaning cotton 213. The water-blocking member 214 has a through hole 2141 extending through the water-blocking member 214 along the first direction. The guide seat 216 is located outside the sliding frame 211 in the third direction. The guide seat 216 is located on one side of the water-blocking member 214 in the third direction and is connected to the water-blocking member 214. A sliding part is formed at the end of the guide seat 216 opposite to the water-blocking member 214. An adjustment groove 401 extending along a second direction is formed on the side wall of the mounting groove 411. The sliding part is adapted to slide with the adjustment groove 401. In the second direction, guide inclined surfaces 4011 are formed at both ends of the adjustment groove 401. The guide inclined surfaces 4011 and the adjustment groove 4011 are connected to the adjustment groove 401. The bottom of the groove 401 is connected to the side wall of the mounting groove 411. The guide slope 4011 extends obliquely away from the middle of the adjusting groove 401 in the direction from the bottom of the adjusting groove 401 toward the side wall of the mounting groove 411. When the sliding part extends into the adjusting groove 401, the through hole 2141 communicates with the water outlet 2121. When the sliding part disengages from the adjusting groove 401 and abuts against the side wall of the mounting groove 411, the water baffle 214 seals the water outlet 2121. The first elastic member 221 extends along a third direction and can be elastically deformed. The two ends of the first elastic member 221 are respectively connected to the guide seat 216 and the sliding frame 211. The first elastic member 221 is configured to always drive the guide seat 216 to press against the side wall of the mounting groove 411 or the inner wall of the adjusting groove 401.

[0045] In this embodiment, a water outlet 2121 is formed on the side of the water storage component 212 facing the cleaning cotton 213. The structure is simple and facilitates the delivery of cleaning fluid, such as screen cleaning fluid, to the cleaning cotton 213. The water-blocking component 214 extends along a third direction and is located between the water storage component 212 and the cleaning cotton 213. The guide seat 216 is located on the outside of the sliding frame 211 in the third direction and is connected to the water-blocking component 214. An adjustment groove 401 extending along a second direction is formed on the side wall of the mounting groove 411. Specifically, the adjustment groove 401 is formed on the side wall of the mounting groove 411 in the third direction. The opening of the adjustment groove 401 faces the display panel 421. The sliding part of the guide seat 216 can extend into the adjustment groove 401 in the third direction. The sliding part of the guide seat 216 slides in cooperation with the adjustment groove 401. During the movement of the cleaning mechanism 20 in the second direction, the adjustment groove 401 can guide and limit the guide seat 216.

[0046] The adjusting groove 401 forms guide slopes 4011 at both ends in the second direction. The guide slopes 4011 are connected to the groove of the adjusting groove 401 and the side wall of the mounting groove 411. The guide slopes 4011 extend inclined away from the middle of the adjusting groove 401 in the direction from the bottom of the adjusting groove 401 toward the side wall of the mounting groove 411. During the vertical movement of the cleaning mechanism 20, the sliding part of the guide seat 216 can enter the adjusting groove 401 along the guide slopes 4011 or exit the adjusting groove 401 along the guide slopes 4011. Since the depth direction of the adjusting groove 401 is perpendicular to the third direction... In the same direction, when the sliding part moves along the guide slope 4011 between the side wall of the mounting groove 411 and the bottom wall of the adjusting groove 401, the water-blocking member 214 can move along the third direction with the movement of the guide seat 216, so that when the sliding part extends into the adjusting groove 401, the through hole 2141 of the water-blocking member 214 can move to communicate with the water outlet 2121. When the sliding part of the water-blocking member 214 disengages from the adjusting groove 401 and abuts against the side wall of the mounting groove 411, the through hole 2141 of the water-blocking member 214 and the water outlet 2121 can be completely misaligned, so that the water-blocking member 214 can close the water outlet 2121.

[0047] The first elastic member 221 extends along a third direction and is elastically deformable. Both ends of the first elastic member 221 are connected to the guide seat 216 and the sliding frame 211, respectively. The first elastic member 221 is configured to always drive the guide seat 216 to press against the side wall of the mounting groove 411 or the inner wall of the adjusting groove 401. This allows the water-blocking member 214 to automatically open or close the water outlet 2121 as the relative position of the cleaning mechanism 20 and the adjusting groove 401 changes in the second direction. For example, the water-blocking member 214 can move between an open position and a closed position, within the guide seat 216. When the sliding part of the guide seat 216 extends into the adjustment groove 401, the guide seat 216 can drive the water-blocking member 214 to move to the open position in the third direction under the action of the first elastic member 221, so that the cleaning liquid can flow out from the water outlet 2121 and flow into the cleaning cotton 213. When the sliding part of the guide seat 216 moves from the adjustment groove 401 to abut against the side wall of the mounting groove 411, the guide seat 216 can overcome the first elastic member 221 and move in the opposite direction under the support of the side wall of the mounting groove 411, thereby driving the water-blocking member 214 to move to the closed position, so that the water outlet 2121 is closed.

[0048] In one example of the invention, reference is made to... Figure 3 , Figure 8 and Figure 9As shown, in the second direction, the two ends of the adjustment groove 401 can extend beyond the two ends of the display panel 421. For example, the guide slope 4011 can be located on both sides of the display panel 421. This allows the through hole 2141 of the water-blocking member 214 to be partially or completely connected to the water outlet 2121 before the cleaning mechanism 20 moves to the display panel 421, so that the cleaning fluid can flow into the cleaning cotton 213 in advance. This allows the cleaning cotton 213 to work with the cleaning fluid to thoroughly clean the display panel 421, resulting in a better and more thorough cleaning effect.

[0049] In one example of the invention, reference is made to... Figure 5 As shown, the cleaning mechanism 20 can move between a first position and a second position. In the first position, the cleaning mechanism 20 is located on the upper side of the display panel 421 and partially within the storage slot 403. In the second position, the cleaning mechanism 20 can be located on the lower side of the display panel 421.

[0050] In this embodiment, the cleaning mechanism 20 is configured to be movable between a first position and a second position. When the cleaning mechanism 20 is in the first position, the storage slot 403 can store the cleaning mechanism 20. The cleaning mechanism 20 can move from the first position to the second position when the cover 200 is open, and move from the second position to the first position when the cover 200 is closed.

[0051] In one example of the present invention, such as Figure 7 and Figure 9 As shown, the guide seat 216 may include a guide frame and a roller 2161. The guide frame is connected to the water baffle 214, and the roller 2161 is rotatably mounted on the guide frame. The roller 2161 is adapted to roll into contact with the inner wall of the adjusting groove 401 and the side wall of the mounting groove 411.

[0052] In this embodiment, the guide seat 216 includes a guide frame and a roller 2161. The guide frame is connected to the water baffle 214, and the roller 2161 is rotatably mounted on the guide frame. The roller 2161 rolls with the side wall of the adjustment groove 401 and the side wall of the mounting groove 411. The structure is simple, so that during the movement of the guide seat 216 in the second direction, the friction between the guide seat 216 and the side wall of the adjustment groove 401 and the side wall of the mounting groove 411 changes from sliding friction to rolling friction, thereby making the movement of the guide seat 216 smoother and more stable, and thus making the movement of the cleaning mechanism 20 smoother.

[0053] For example, refer to Figure 5 and Figure 7As shown, one end of the guide frame mounting roller 2161 can be the sliding part of the guide seat 216, and one end of the guide frame can cooperate with the roller 2161 to extend into the adjustment groove 401. The guide frame can include a connecting section and a fixed section. One end of the connecting section is connected to the water baffle 214, and the other end of the connecting section extends along the first direction toward the bottom wall of the mounting groove 411 in the first direction. The fixed section extends along the third direction and is connected to the other end of the connecting section. The roller path is rotatably provided in the fixed section. The end face of the fixed section in the third direction toward the adjustment groove 401 can be set as an arc surface that matches the roller 2161 to reduce the probability of interference with the side wall of the adjustment groove 401 or the mounting groove 411, so that the roller 2161 can roll more stably and smoothly along the guide slope 4011 to the side wall of the mounting groove 411 or the bottom wall of the adjustment groove 401 in the third direction.

[0054] The first elastic element 221 can be connected between the connecting section and the sliding frame 211. The sliding frame 211 can be provided with a clearance hole so that the water-blocking element 214 can pass through the sliding frame 211 and connect with the guide frame. The clearance hole can also play a certain limiting and guiding role in the movement of the water-blocking element 214, so that the water-blocking element 214 can move stably in a third direction under the cooperation of the guide seat 216 and the first elastic element 221.

[0055] refer to Figure 7 As shown, in this embodiment, in the first direction, the fixing section can extend beyond the cleaning cotton 213. The bottom wall of the mounting groove 411 in the first direction can also be provided with a sliding groove 402. The fixing section can extend into the sliding groove 402 and slide in cooperation with the sliding groove 402. The sliding groove 402 can communicate with the adjustment groove 401 in the third direction, so that the sliding part of the guide seat 216 can smoothly extend into the adjustment groove 401 in the third direction.

[0056] In one example of the invention, reference is made to... Figure 3 and Figure 5 As shown, the cleaning assembly 100 may also include a limiting member 224, which extends in a second direction and is disposed in the mounting groove 411 and connected to the inner wall of the mounting groove 411. In the first direction, the limiting member 224 is disposed on the side of the guide seat 216 facing the opening of the mounting groove 411.

[0057] In this embodiment, the cleaning component 100 is further provided with a limiting member 224. The limiting member 224 extends along the second direction and is connected to the inner wall of the mounting groove 411. For example, the two ends of the limiting member 224 can be connected to the upper side wall and the lower side wall of the mounting groove 411, respectively. In the first direction, the limiting member 224 is disposed on the side of the guide seat 216 facing the opening of the mounting groove 411. The guide seat 216 is arranged between the limiting member 224 and the bottom wall of the mounting groove 411 in the first direction. The limiting member 224 can cooperate with the sliding groove 402 to effectively limit the guide seat 216 in the first direction, thereby preventing the guide seat 216 from being blocked. The movement of the guide seat 216 in the first direction allows the guide seat 216 to move stably and reliably in the second direction, and the relative position of the sliding frame 211 and the display panel 421 in the first direction can be limited to a certain extent. During the process of the cleaning mechanism 20 moving in the second direction to clean the display panel 421, the cleaning cotton 213 can stably and reliably contact the surface of the display panel 421 and form a relatively stable squeezing effect to carry out the cleaning operation. Thus, the cleaning mechanism 20 can effectively clean the display panel 421 to a certain extent, and improve the stability of the cleaning component 100 during operation.

[0058] In one example of the invention, reference is made to... Figure 8 and Figure 9 As shown, in the third direction, the thickness of the water-blocking member 214 gradually decreases away from the guide seat 216. The cleaning mechanism 20 also includes a squeezing member 215, which extends along the third direction and is located between the water storage member 212 and the water-blocking member 214. The squeezing member 215 is fixedly connected to the water storage member 212 and abuts against the water-blocking member 214. The squeezing member 215 is provided with a through hole 2151, which penetrates the squeezing member 215 along the first direction and is arranged opposite to the water outlet 2121. The thickness of the squeezing member 215 gradually increases away from the guide seat 216 in the first direction.

[0059] In this embodiment, the thickness of the water-blocking member 214 gradually decreases in the first direction away from the guide seat 216 in the third direction, and the thickness of the extrusion member 215 gradually increases in the first direction away from the guide seat 216 in the third direction. For example, in the first direction, the surface of the extrusion member 215 facing the water-blocking member 214 can be a slope, and the surface of the water-blocking member 214 facing the extrusion member 215 can be a slope. When the sliding part of the guide seat 216 of the cleaning mechanism 20 disengages from the adjustment groove 401 and moves to abut against the side wall of the mounting groove 411, the water-blocking member 214 moves away from the adjustment groove 401 relative to the extrusion member 215 in the third direction. Due to the limiting member 224 limiting the guide seat 216 in the first direction, the water-blocking member 214 and the extrusion member 215 can be gradually pressed together in the first direction, so that when the cleaning mechanism 20 moves to the first position, the water-blocking member 214 can more stably and reliably block the water outlet 2121 of the water storage member 212.

[0060] In one example of the invention, reference is made to... Figure 7 , Figure 8 and Figure 10 As shown, the cleaning mechanism 20 may also include: a support plate 217 and a second elastic element 222, a scraper 219 and a positioning plate 218, and a third elastic element 223.

[0061] Specifically, the length direction of the support plate 217 is in the same direction as the third direction, and the thickness direction of the support plate 217 is in the same direction as the first direction. The support plate 217 is located between the water storage component 212 and the cleaning cotton 213 and is connected to the cleaning cotton 213. The second elastic member 222 is located between the support plate 217 and the water storage component 212, and the second elastic member 222 can elastically deform along the first direction. The length direction of the positioning plate 218 is in the same direction as the third direction, and the thickness direction of the positioning plate 218 is in the same direction as the second direction. The positioning plate 218 is located between the support plate 217 and the cleaning cotton. On the upper side of 213, the positioning plate 218 is connected to the sliding frame 211, and the scraper 219 is located on the side of the positioning plate 218 away from the support plate 217. One end of the scraper 219 is rotatably connected to the sliding frame 211, and the other end of the scraper 219 extends upward in a first direction away from the water storage component 212. In the first direction, the other end of the scraper 219 extends beyond the cleaning cotton 213. The third elastic member 223 can elastically deform along the second direction. The two ends of the third elastic member 223 are respectively connected to the top wall of the sliding frame 211 and the scraper 219.

[0062] In this embodiment, the cleaning mechanism 20 further includes a support plate 217. The thickness direction of the support plate 217 is in the same direction as the first direction, and the length direction of the support plate 217 is in the same direction as the third direction. The support plate 217 is disposed between the water storage component 212 and the cleaning cotton 213 and is connected to the cleaning cotton 213. The second elastic member 222 is disposed between the support plate 217 and the water storage component 212 and can elastically deform along the first direction. The structure is simple and can provide good support and cushioning for the cleaning cotton 213 in the first direction. During the process of the cleaning mechanism 20 moving along the second direction to clean the display panel 421, the cleaning cotton 213 can be supported by the second elastic member 222 and the support plate 217. Under the action of the cleaning mechanism 20, the cleaning cotton 213 makes stable and reliable contact with the display panel 421 and forms a stable abutment and clamping, so that the cleaning cotton 213 can effectively clean the dirt on the display panel 421 as the cleaning mechanism 20 moves. The setting of the second elastic element 222 allows the cleaning cotton 213 to adapt well to the surface undulations and surface differences of the display panel 421 and the bottom wall of the mounting groove 411 in the first direction, so that the cleaning cotton 213 can always stably abut against the surface of the display panel 421 and the bottom wall of the mounting groove 411, thereby making the movement of the cleaning mechanism 20 more stable to a certain extent, and making the cleaning component 100 operate more stably and reliably.

[0063] In this embodiment, the cleaning mechanism 20 also includes a scraper 219 and a positioning plate 218. The positioning plate 218 is located on the upper side of the support plate 217 and the cleaning cotton 213 and is connected to the sliding frame 211. The positioning plate 218 can work with the sliding frame 211 to effectively limit and fix the cleaning cotton 213 and the support plate 217, reduce the movement of the support plate 217 and the cleaning cotton 213 in the second direction, and enable the support plate 217 and the cleaning cotton 213 to move more stably along the first direction for cleaning operations.

[0064] The scraper 219 is positioned on the side of the positioning plate 218 away from the support plate 217, which is a reasonable arrangement. One end of the scraper 219 is rotatably connected to the sliding frame 211, and the other end of the scraper 219 extends upward in a first direction away from the water storage component 212. The scraper 219 is connected to the top wall of the sliding frame 211 through a third elastic element 223. The structure is simple. During the process of the cleaning mechanism 20 moving from top to bottom, the cleaning cotton 213, together with the input cleaning fluid, cleans the display panel 421, resulting in a large number of liquid droplets remaining on the cleaned display panel 421. This interferes with the operator's viewing of the information displayed on the display panel 421. The scraper 219 is positioned above the cleaning cotton 213, which can scrape off the liquid droplets on the display panel 421 after the cleaning cotton 213 has cleaned it, thereby reducing liquid droplet residue and facilitating display. The use of panel 421, exemplarily, allows the scraper 219 to effectively cooperate with the display panel 421 and the mounting groove 411 in the first direction by compression and stretching of the third elastic member 223, which can ensure that the other end of the scraper 219 can always stably and reliably abut against the display panel 421 for scraping operations under the action of the third elastic member 223. The other end of the scraper 219 extends upward, which facilitates the scraper 219 to rotate around the rotation axis of one end, so that the scraper 219 can stably abut against the display panel 421. The other end of the scraper 219 can be formed with a bevel that cooperates with the display panel 421, thereby increasing the contact area with the display panel 421 and reducing the probability of the scraper 219 scratching and damaging the display panel 421.

[0065] When the cleaning mechanism 20 moves from bottom to top, the positioning plate 218 can limit the rotation of the scraper 219, allowing the scraper 219 to rotate within a suitable range, thus making the operation of the scraper 219 more stable.

[0066] In some specific embodiments of the present invention, reference is made to... Figure 5 and Figure 6 As shown, the cleaning mechanism 20 also includes a cleaning roller 225, which extends in a third direction and is located on the lower side of the display panel 421. A cleaning groove is also formed on the bottom wall of the mounting groove 411 in the first direction. The cleaning roller 225 is rotatably disposed in the cleaning groove, and in the first direction, a portion of the cleaning roller 225 protrudes from the opening of the cleaning groove. The cleaning roller 225 is used to remove sewage from the scraper 219.

[0067] In this embodiment, the cleaning mechanism 20 also includes a cleaning roller 225. The cleaning roller 225 is disposed on the lower side of the display panel 421 and arranged in the cleaning groove. Part of the cleaning roller 225 protrudes from the opening of the cleaning groove. The cleaning roller 225 is used to remove sewage from the scraper 219. The arrangement is reasonable. During the cleaning process of the cleaning mechanism 20 cleaning the display panel 421 from top to bottom, the residual liquid droplets on the display panel 421 gradually gather and form sewage as the scraper 219 moves downward. The sewage flows downward along the display panel 421. When the cleaning mechanism 20 moves to the second position, the cleaning roller 225 can remove the sewage accumulated at the scraper 219 and the sewage flowing down.

[0068] For example, the cleaning roller 225 can be a cotton roller, allowing sewage to be absorbed onto the cleaning roller 225. The cleaning roller 225 is rotatably disposed in the cleaning trough and partially protrudes from the opening of the cleaning trough. During the downward movement of the cleaning mechanism 20, the cleaning cotton 213 can contact the peripheral surface of the cleaning roller 225 in the first direction. The cleaning cotton 213 can continue to move downward smoothly over the cleaning roller 225 by compression of the second elastic member 222. During the process of the cleaning cotton 213 passing over the cleaning roller 225, the water generated by the squeezing of the cleaning cotton 213 can be absorbed by the cleaning roller 225. The other end of the scraper 219 can abut against the cleaning roller 225 in the second direction. As the cleaning mechanism 20 continues to move, the scraper 219 squeezes and rotates with the cleaning roller 225, so that the cleaning roller 225 can stably remove the sewage at the scraper 219. Furthermore, when the cleaning mechanism 20 is in the second position, the scraper 219 can be in a state of compression with the cleaning roller 225, and the other end of the scraper 219 can be on the upper side of the cleaning roller 225. This can effectively prevent the scraper 219 from getting stuck with the cleaning roller 225 when the cleaning mechanism 20 moves from bottom to top, so that the scraper 219 can smoothly disengage from the cleaning roller 225, thereby making the operation of the cleaning assembly 100 more stable.

[0069] In one specific embodiment of the present invention, the cleaning roller 225 is detachably installed in the cleaning groove, which facilitates the disassembly and assembly of the cleaning roller 225, and allows the cleaning roller 225 to be easily removed from the cleaning groove for cleaning or replacement when cleaning is required.

[0070] In some embodiments of the present invention, reference is made to Figure 11As shown, the hydrogen power generation equipment 400 may further include: a hydrogen storage tank, a hydrogen generator set, a hydrogen storage device, and a delivery pipeline. The hydrogen storage tank, hydrogen generator set, hydrogen storage device, and delivery pipeline are all housed within the enclosure 410. The monitoring system 420 may further include: a hydrogen concentration sensor 423, a temperature sensor 424, a pressure sensor 425, an alarm device 422, and a controller. The hydrogen concentration sensor 423 is used to detect the hydrogen concentration around the hydrogen storage tank and at pipeline connections. The temperature sensor 424 is distributed and installed on the hydrogen generator set. The pressure sensor 425 is installed on the hydrogen storage device and the delivery pipeline. The alarm device 422 is installed in the enclosure 410. The hydrogen concentration sensor 423, temperature sensor 424, and pressure sensor 425 are all electrically connected to the display panel 421 and the alarm device 422 via the controller. This meets the operational needs of the hydrogen power generation equipment 400.

[0071] In some embodiments of the present invention, such as Figure 3 and Figure 5 As shown, the hydrogen power generation equipment 400 installation monitoring device may also include a support rod 300, which is telescopic. There are two support rods 300, which are arranged at intervals in a third direction. The two ends of the support rods 300 are rotatably connected to the inner wall of the mounting groove 411 and the first end of the cover plate 200, respectively.

[0072] In this embodiment, a retractable support rod 300 is provided to connect the cover plate 200 and the inner wall of the mounting groove 411. The structure is simple and can provide good support after the cover plate 200 is opened. For example, the support rod 300 can be a gas strut, specifically, the support rod 300 can be a gas spring with a self-locking function. The support rod 300 is hinged to the side wall of the mounting groove 411 in the first direction. One end of the support rod 300 connected to the mounting groove 411 can be located in the middle of the mounting groove 411 in the second direction. The support rod 300 can be arranged on both sides of the display panel 421 in the third direction to provide stable support for the cover plate 200 and facilitate the assembly of the display panel 421 with the display panel 421 in the mounting groove 411.

[0073] The following will refer to Figures 1-11 A safety monitoring device 1000 for hydrogen power generation equipment according to a specific embodiment of the present invention is described.

[0074] like Figures 1-11As shown, the hydrogen power generation equipment safety monitoring device 1000 is a hydrogen power generation vehicle. The hydrogen power generation equipment safety monitoring device 1000 may include a vehicle body, a hydrogen power generation device 400, a cover plate 200, a support rod 300, and a cleaning component 100. The hydrogen power generation device 400 includes a housing 410 and a monitoring system 420. The housing 410 may house a hydrogen storage tank, a hydrogen generator set, a hydrogen storage device, and a delivery pipeline. The monitoring system 420 may include a hydrogen concentration sensor 423, a temperature sensor 424, a pressure sensor 425, an alarm device 422, a controller, and a display panel 421. The hydrogen concentration sensor 423, temperature sensor 424, and pressure sensor 425 are arranged in corresponding positions within the housing 410 or on the vehicle body as needed, and are electrically connected to the display panel 421 and the alarm device 422 via the controller.

[0075] The housing 410 has a mounting groove 411 formed on one side in a first direction, which is the width direction of the hydrogen power generation vehicle. The second direction is the vertical direction, and the third direction is the front-to-back direction of the hydrogen power generation vehicle. A storage groove 403 is formed on the upper side wall of the mounting groove 411 in the second direction. An adjustment groove 401 is formed on one side wall of the mounting groove 411 in the third direction. A sliding groove 402 communicating with the adjustment groove 401 is formed on the bottom wall of the mounting groove 411 in the first direction.
