[0045] like Figure 1 As shown, the safety monitoring device 1000 for hydrogen power generation equipment according to an embodiment of the present invention includes: hydrogen power generation equipment 400, a cover plate 200 and a cleaning assembly 100. The hydrogen power generation equipment 400 includes: a box 410 and a monitoring system 420. The box 410 is in a first direction (such as Figure 2A mounting slot 411 is provided on one side (in the left and right directions shown in FIG), and the monitoring system 420 includes a display panel 421, which is installed in the mounting slot 411; the cover 200 is installed on the box body 410, and the cover 200 is openably covered on the opening of the mounting slot 411; the cleaning assembly 100 is provided in the mounting slot 411, and the cleaning assembly 100 includes a winding mechanism 10 and a cleaning mechanism 20, wherein the cover 200 is configured to drive the cleaning mechanism 20 along the second direction (as shown in FIG) when it is opened. Figure 2 The winding mechanism 10 is configured to drive the cleaning mechanism 20 to move along a second direction to clean the display panel 421 when the cover 200 is closed, and the second direction intersects with the first direction.

[0046] In this embodiment, the safety monitoring device 1000 for hydrogen power generation equipment includes a hydrogen power generation equipment 400, a cover plate 200, and a cleaning assembly 100. The hydrogen power generation equipment 400 is provided with a box 410 and a monitoring system 420. For example, the box 410 can be installed with devices such as a hydrogen power generation system, a hydrogen storage system, and conveying structures such as pipelines to meet the operating needs of the hydrogen power generation equipment 400.

[0047] The box body 410 is provided with a mounting groove 411 on one side in the first direction, and the cover plate 200 is openably provided to cover 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 energy power generation equipment 400, the operator can open the cover plate 200 to view the information on the display panel 421. After the use of the hydrogen energy power generation equipment 400 is finished, 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.

[0048] In this embodiment, a cleaning assembly 100 is also provided. The cleaning assembly 100 is arranged in the mounting groove 411 and includes a winding mechanism 10 and a cleaning mechanism 20. The cover 200 is configured to drive the cleaning mechanism 20 to move along the second direction to clean the display panel 421 when it is opened. 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 200 is closed. For example, when the cover 200 is in a closed state, the cleaning mechanism 20 can be located on one side of the display panel 421 in the second direction. During the process of opening the cover 200, the cover 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. When the cover 200 drives the cleaning mechanism 20 to move along the second direction, the cleaning mechanism 20 can be driven by 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 mechanism 20 moves from one side of the display panel 421 to the other side, the cleaning mechanism 20 completes cleaning the display panel 421, and the operator can view and use the display panel 421 normally. After the use of the hydrogen energy power generation equipment 400 is finished, 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. In this way, dust, sewage and other dirt accumulated on the display panel 421 during the use of the hydrogen energy power generation equipment 400 can be effectively removed, and the cleaning mechanism 20 can be restored to its initial position, so that the cleaning mechanism 20 can continue to clean the display panel 421 when the hydrogen energy power generation equipment 400 is used next time.

[0049] In this embodiment, when the cover 200 is opened, the cleaning mechanism 20 is driven to move and clean the display panel 421. When the cover 200 is closed, the winding mechanism 10 drives the cleaning mechanism 20 to move and reset and clean the display panel 421 again, so that the display panel 421 can be well cleaned. In addition, when the hydrogen power generation equipment 400 is in use, the operator can complete the cleaning of the display panel 421 in the process of opening and closing the cover 200, which greatly saves the manpower and time consumption during manual cleaning, and can achieve a senseless cleaning effect to a certain extent, thereby making the cleaning of the display panel 421 more time-saving and trouble-free, and making the use of the hydrogen power generation equipment 400 more convenient and efficient.

[0050] In this embodiment, the second direction intersects the first direction, which is intended to illustrate that the first direction and the second direction may be arranged perpendicularly, or may only intersect in a non-perpendicular arrangement.

[0051] According to the safety monitoring device 1000 of the hydrogen power generation equipment according to the embodiment of the present invention, a cleaning component 100 is provided, and the cleaning component 100 includes a cleaning mechanism 20 and a winding mechanism 10. The cover 200 is configured to drive the cleaning mechanism 20 to move along the second direction to clean the display panel 421 when it is opened, 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 200 is closed. When the hydrogen power generation equipment 400 is in use, the operator can complete the cleaning of the display panel 421 in the process of opening and closing the cover 200, which greatly saves the manpower and time consumed in manual cleaning, thereby making the cleaning of the display panel 421 more time-saving and trouble-free, and making the use of the hydrogen power generation equipment 400 more convenient and efficient.

[0052] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the cover plate 200 has a first end and a second end at both ends in the second direction, the first end is rotatably connected to the box body 410, and the rotation axis of the first end is along the third direction (such as Figure 5 The third direction intersects the second direction and the first direction in pairs. The winding mechanism 10 may include: a first traction rope 13, a winding drum 11 and a spiral spring 12, a second traction rope 14 and a guide block 15.

[0053] Specifically, one end of the first traction rope 13 is connected to the cleaning mechanism 20; the winding drum 11 extends along the third direction and is rotatably arranged in the installation groove 411, one end of the spiral spring 12 is connected to the winding drum 11, and the other end of the spiral spring 12 is connected to the inner wall of the installation groove 411. In the second direction, the winding drum 11 and the first end are located on the same side of the display panel 421 in the second direction, and the other end of the first traction rope 13 is wound around the winding drum 11; one end of the second traction rope 14 is connected to the cleaning assembly 100, and the second traction rope 14 is connected to the cleaning assembly 100. The other end is connected to the second end of the cover 200, and the cover 200 is configured to drive the cleaning mechanism 20 away from the winding drum 11 through the second traction rope 14 when it is opened; the guide block 15 is arranged on the other side of the display panel 421 in the second direction, and the guide block 15 is provided with a guide groove 151, and the second traction rope 14 is passed 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 200.

[0054] In this embodiment, the two ends of the cover 200 in the second direction are respectively a first end and a second end, and the first end is rotatably connected to the box body 410. For example, the cover 200 can be hingedly connected to the box body 410 through the first end. For example, the opening periphery of the installation groove 411 can form an edge sealing groove that cooperates with the cover 200. When the cover 200 is in a closed state, the outer surface of the cover 200 in the first direction can be flush with the surface of the box body 410, so that the cover 200 can stably close the installation groove 411.

[0055] The rotation axis of the first end extends along the third direction. When the cover 200 is opened, the second end of the cover 200 rotates around the rotation axis of the first end along the first direction and the second direction away from the opening of the mounting groove 411. For example, after the cover 200 is fully opened, the second end of the cover 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 greatly reduce the obstruction of the display panel 421 by the cover 200, so that the operator can conveniently view and use the display panel 421.

[0056] In this embodiment, the third direction intersects with the second direction and the first direction in pairs, which is intended to illustrate that the first direction and the second direction can be arranged vertically, or can be arranged in a non-vertical arrangement with only intersection, the first direction and the third direction can be arranged vertically, or can be arranged in a non-vertical arrangement with only intersection, and the second direction and the third direction can be arranged vertically, or can be arranged in a non-vertical arrangement with only intersection.

[0057] In this embodiment, the first end 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 arranged in the installation 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 installation groove 411. The spiral spring 12 plays a role in resetting the winding drum 11, so that the winding drum 11 rotates a certain angle under the action of an external force. When the external force disappears, the winding drum 11 can be reversed and rotated 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 winding drum 11. When the cleaning mechanism 20 moves away from the winding drum 11 in the second direction, the first traction rope 13 unfolds in the second direction and drives the winding drum 11 to rotate. When the cleaning mechanism 20 approaches the winding drum 11 in the second direction, the winding drum 11 can be reversed and wound around the first traction rope 13 under the action of the spiral spring 12, so that the first traction rope 13 is wound onto the winding drum 11.

[0058] One end of the second traction rope 14 is connected to the cleaning component 100 and the other end is connected to the second end of the cover 200. The cover 200 is configured to drive the cleaning mechanism 20 away from the winding drum 11 through the second traction rope 14 when it is opened. For example, 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 when the cover 200 is in a closed state. When the cover 200 is opened, 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.

[0059] The guide block 15 in this embodiment is arranged on the other side of the display panel 421 in the second direction, and the guide block 15 is provided with a guide groove 151. The guide groove 151 has a first opening and a second opening. The first opening is directed toward the display panel 421 in the second direction, and the second opening is directed toward 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. In the process of opening the cover plate 200, the second traction rope 14 is guided and limited by the guide groove 151, and the second traction rope 14 is located between the cleaning mechanism 20 and the guide block. The portion between 15 can be stably moved along the second direction, so that the cleaning mechanism 20 can be stably moved along the second direction from one side of the display panel 421 to the other side for cleaning. When the cover 200 is closed, the force applied to the cleaning mechanism 20 by the cover 200 through the second traction rope 14 gradually decreases, so that the winding drum 11 and the spiral spring 12 can cooperate with the first traction rope 13 to stably drive the cleaning mechanism 20 to move along the second direction from the other side of the display panel 421 to one side for cleaning, so that the cleaning mechanism 20 can clean the display panel 421 stably, reliably and effectively.

[0060] In some examples of the present invention, reference Figure 4 and Figure 7 As shown, the second direction is the up-down direction, and the upper side wall of the installation groove 411 may be formed with a receiving groove 403 , and the winding drum 11 and the spiral spring 12 may be disposed in the receiving groove 403 .

[0061] In this embodiment, the winding drum 11 and the spiral spring 12 are arranged in the storage groove 403. For example, the winding mechanism 10 can also include a shell, which is fixed in the storage groove 403 with the opening facing downward. The winding drum 11 and the spiral spring 12 can be arranged in the shell, and the other end of the spiral spring 12 can be connected to the inner wall of the shell, which can facilitate the installation and arrangement of the winding drum 11 and the spiral spring 12.

[0062] In one embodiment of the present invention, reference Figure 4 、 Figure 5 and Figure 7As shown, the second direction is the up and down direction, the winding drum 11 is arranged on the upper side of the display panel 421, and the cleaning mechanism 20 may include: a sliding frame 211, cleaning cotton 213 and a water storage part 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 winding drum 11, and one end of the second traction rope 14 is connected to the side of the sliding frame 211 away from the winding drum 11; the cleaning cotton 213 is arranged on the sliding frame 211, and the cleaning cotton 213 is suitable for contacting with the display panel 421 to clean the display panel 421, and the water storage part 212 is arranged 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, and the water storage part 212 is used to transport cleaning liquid to the cleaning cotton 213.

[0063] In this embodiment, the second direction is the up and down direction, and the winding drum 11 is arranged on the upper side of the display panel 421. When the cover 200 is in the closed state, the cleaning mechanism 20 is located on the upper side of the display panel 421, and when the cover 200 is in the open state, the cleaning mechanism 20 is located on the lower side of the display panel 421. When the cover 200 is opened, the cleaning mechanism 20 cleans the display panel 421 from top to bottom, and when the cover 200 is closed, the cleaning mechanism 20 cleans the display panel 421 from bottom to top.

[0064] In this embodiment, the cleaning mechanism 20 includes a sliding frame 211, cleaning cotton 213 and a water storage part 212. The sliding frame 211 extends along 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.

[0065] The cleaning cotton 213 and the water storage component 212 in this embodiment are both arranged on the sliding frame 211. For example, the sliding frame 211 can form a accommodating space that passes through along the first direction, and the cleaning cotton 213 and the water storage component 212 are installed in the accommodating space. The setting of the sliding frame 211 can facilitate the installation and arrangement of the cleaning cotton 213 and the water storage component 212, and facilitate 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.

[0066] In this embodiment, the cleaning cotton 213 is suitable for contacting the display panel 421 to clean the display panel 421. The water storage part 212 is located on the side of the cleaning cotton 213 away from the cleaning cotton 213 in the first direction and transports cleaning liquid to the cleaning cotton 213. The structure is simple and the arrangement is reasonable, so that the cleaning cotton 213 can cooperate with the cleaning liquid to achieve a better cleaning effect on the display panel 421 when cleaning the display panel 421.

[0067] In some examples of the present invention, Figure 7 and Figure 8 As shown, the water storage member 212 is formed with a water outlet 2121 on one side facing the cleaning cotton 213 in the first direction. The cleaning mechanism 20 may further include: a water blocking member 214 , a guide seat 216 and a first elastic member 221 .

[0068] Specifically, the water blocking member 214 extends along the third direction. In the first direction, the water blocking member 214 is arranged between the water storage member 212 and the cleaning cotton 213. The water blocking member 214 is provided with a through hole 2141 that penetrates the water blocking member 214 along the first direction; the guide seat 216 is located on the outside of the sliding frame 211 in the third direction, and the guide seat 216 is arranged on one side of the water blocking member 214 in the third direction and is connected to the water blocking member 214. A sliding portion is formed on the end of the guide seat 216 that faces away from the water blocking member 214, and an adjusting groove 401 extending along the second direction is formed on the side wall of the mounting groove 411. The sliding portion is suitable for slidingly cooperating with the adjusting groove 401, wherein, in the second direction, guide slopes 4011 are respectively formed at both ends of the adjusting groove 401, and the guide slopes 4011 are aligned with the adjusting groove 401. The bottom of the section groove 401 is connected to the side wall of the installation groove 411, and the guide slope 4011 extends obliquely away from the middle of the adjustment groove 401 in the direction from the bottom of the adjustment groove 401 toward the side wall of the installation groove 411. When the sliding part extends into the adjustment groove 401, the through hole 2141 is connected with the water outlet 2121. When the sliding part disengages from the adjustment groove 401 and abuts against the side wall of the installation groove 411, the water stop 214 closes the water outlet 2121; the first elastic part 221 extends along the third direction and can be elastically deformed. The two ends of the first elastic part 221 are respectively connected to the guide seat 216 and the sliding frame 211. The first elastic part 221 is configured to always drive the guide seat 216 to press toward the side wall of the installation groove 411 or the inner wall of the adjustment groove 401.

[0069] In this embodiment, a water outlet 2121 is formed on the side of the water storage member 212 facing the cleaning cotton 213. This simple structure facilitates the delivery of cleaning liquid, such as screen cleaning liquid, to the cleaning cotton 213. The water retaining member 214 extends along the third direction and is located between the water storage member 212 and the cleaning cotton 213. The guide seat 216 is located outside the sliding frame 211 in the third direction and is connected to the water retaining member 214. The sidewall of the mounting groove 411 is formed with an adjustment groove 401 extending along the second direction. Specifically, the sidewall of the mounting groove 411 is formed with the adjustment groove 401 in the third direction, and the opening of the adjustment groove 401 faces the display panel 421. The sliding portion of the guide seat 216 can extend into the adjustment groove 401 along the third direction. The sliding portion of the guide seat 216 slidably cooperates with the adjustment groove 401. During the movement of the cleaning mechanism 20 in the second direction, the adjustment groove 401 can serve as a guide and limiter for the guide seat 216.

[0070] The adjusting groove 401 forms a guiding inclined surface 4011 at both ends of the second direction, and the guiding inclined surface 4011 is connected to the groove of the adjusting groove 401 and the side wall surface of the installation groove 411. The guiding inclined surface 4011 extends obliquely away from the middle part of the adjusting groove 401 in the direction from the groove bottom of the adjusting groove 401 toward the side wall surface of the installation groove 411. When the cleaning mechanism 20 moves in the up and down directions, the sliding portion of the guide seat 216 can enter the adjusting groove 401 along the guiding inclined surface 4011 or exit the adjusting groove 401 from the adjusting groove 401 along the guiding inclined surface 4011. Since the depth direction of the adjusting groove 401 is the same as that of the third direction, In the same direction, when the sliding portion moves along the guide slope 4011 between the side wall of the installation groove 411 and the bottom wall of the adjustment groove 401, the water stop 214 can move along the third direction with the movement of the guide seat 216, so that when the sliding portion of the water stop 214 extends into the adjustment groove 401, the through hole 2141 of the water stop 214 can move to connect with the water outlet hole 2121. When the sliding portion of the water stop 214 detaches from the adjustment groove 401 and abuts against the side wall of the installation groove 411, the through hole 2141 of the water stop 214 and the water outlet hole 2121 can be completely staggered, so that the water stop 214 can close the water outlet hole 2121.

[0071] The first elastic member 221 extends along the 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 toward the side wall of the installation groove 411 or the inner wall of the adjustment groove 401. In this way, the water retaining member 214 can automatically open or close the water outlet 2121 as the relative position of the cleaning mechanism 20 and the adjustment groove 401 in the second direction changes. For example, the water retaining member 214 can move between the open position and the closed position. When the sliding portion of the guide seat 216 extends into the adjusting groove 401, the guide seat 216 can drive the water retaining member 214 to move to the open position along 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 portion of the guide seat 216 moves from the adjusting groove 401 to abut against the side wall of the installation groove 411, the guide seat 216 can overcome the reverse movement of the first elastic member 221 under the support of the side wall of the installation groove 411, thereby driving the water retaining member 214 to move to the closed position, so that the water outlet 2121 is closed.

[0072] In one example of the present invention, reference Figure 3 、 Figure 8 and Figure 9As shown, in the second direction, both ends of the adjustment groove 401 may extend beyond both ends of the display panel 421. For example, the guide slopes 4011 may be located on both sides of the display panel 421. This allows the through hole 2141 of the water retaining member 214 to be partially or completely connected to the water outlet 2121 before the cleaning mechanism 20 moves to the display panel 421, thereby allowing the cleaning liquid to flow into the cleaning cotton 213 in advance. The cleaning cotton 213 and the cleaning liquid can cooperate to fully clean the display panel 421, thereby achieving a better and more thorough cleaning effect on the display panel 421.

[0073] In one example of the present invention, reference 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 located in the storage groove 403. In the second position, the cleaning mechanism 20 can be on the lower side of the display panel 421.

[0074] 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 groove 403 can serve as a storage for the cleaning mechanism 20. The cleaning mechanism 20 can move from the first position to the second position when the cover 200 is opened, and move from the second position to the first position when the cover 200 is closed.

[0075] In one example of the present invention, 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 blocking member 214, the roller 2161 is rotatably arranged on the guide frame, and the roller 2161 is suitable for rolling cooperation with the inner wall of the adjustment groove 401 and the side wall of the installation groove 411.

[0076] In this embodiment, the guide seat 216 includes a guide frame and a roller 2161. The guide frame is connected to the water barrier 214. The roller 2161 is rotatably arranged on the guide frame. The roller 2161 rolls with the side walls of the adjustment groove 401 and the side walls of the installation groove 411. The structure is simple. During the movement of the guide seat 216 along the second direction, the friction between the guide seat 216 and the side walls of the adjustment groove 401 and the side walls of the installation 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 and smoother.

[0077] 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 may include a connecting section and a fixed section, one end of the connecting section is connected to the water stop 214, and the other end of the connecting section extends along the first direction toward the bottom wall of the installation groove 411 in the first direction, and the fixed section extends along the third direction and is connected to the other end of the connecting section, and the roller path is rotatably provided on the fixed section, wherein the end face of the fixed section in the third direction facing the adjustment groove 401 can be set to a circular arc surface matching the roller 2161 to reduce the probability of interference with the side wall of the adjustment groove 401 or the installation groove 411, so that the roller 2161 can roll more stably and smoothly along the guide inclined surface 4011 to the side wall surface of the installation groove 411 or the bottom wall surface of the adjustment groove 401 in the third direction.

[0078] The first elastic member 221 can be connected between the connecting section and the sliding frame 211, and the sliding frame 211 can be provided with an avoidance hole so that the water blocking member 214 can pass through the sliding frame 211 and be connected to the guide frame. The avoidance hole can also play a certain limiting and guiding role in the movement of the water blocking member 214, so that the water blocking member 214 can move stably along the third direction under the cooperation of the guide seat 216 and the first elastic member 221.

[0079] refer to Figure 7 As shown, in this embodiment, in the first direction, the fixed section can be arranged beyond the cleaning cotton 213, and the bottom wall of the mounting groove 411 in the first direction can also be provided with a sliding groove 402, and the fixed section can be extended into the sliding groove 402 and slideably cooperate with the sliding groove 402, and the sliding groove 402 can be connected with the adjusting groove 401 in the third direction, so that the sliding portion of the guide seat 216 can smoothly extend into the adjusting groove 401 along the third direction.

[0080] In one example of the present invention, reference Figure 3 and Figure 5 As shown, the cleaning assembly 100 may also include a limit member 224, which extends along the second direction. The limit member 224 is arranged in the mounting groove 411 and is connected to the inner wall of the mounting groove 411. In the first direction, the limit member 224 is arranged on the side of the guide seat 216 facing the opening of the mounting groove 411.

[0081] In this embodiment, the cleaning component 100 is further provided with a limit member 224, which extends along the second direction and is connected to the inner wall of the installation groove 411. For example, the two ends of the limit member 224 can be respectively connected to the upper side wall and the lower side wall of the installation groove 411. In the first direction, the limit member 224 is arranged on the side of the opening of the guide seat 216 facing the installation groove 411, and the guide seat 216 is arranged between the limit member 224 and the bottom wall of the installation groove 411 in the first direction. The limit member 224 can cooperate with the sliding groove 402 to limit the guide seat 216 in the first direction, thereby avoiding the guide seat 216 from sliding. The movement of the guide seat 216 in the first direction allows the guide seat 216 to move stably and reliably along the second direction, and the relative positions of the sliding frame 211 and the display panel 421 in the first direction can be limited to a certain extent, so that during the movement of the cleaning mechanism 20 along 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 perform the cleaning operation, so that the cleaning mechanism 20 can effectively clean the display panel 421 to a certain extent, thereby improving the stability of the cleaning component 100 during operation.

[0082] In one example of the present invention, reference Figure 8 and Figure 9 As shown, in the third direction, the thickness dimension of the water retaining member 214 in the first direction gradually decreases away from the guide member, and the cleaning mechanism 20 also includes an extrusion member 215, which extends along the third direction. The extrusion member 215 is arranged between the water storage member 212 and the water retaining member 214, and the extrusion member 215 is fixedly connected to the water storage member 212. The extrusion member 215 abuts against the water retaining member 214, and the extrusion member 215 is provided with a through hole 2151, which passes through the extrusion member 215 along the first direction and is arranged opposite to the water outlet hole 2121, wherein the thickness dimension of the extrusion member 215 in the first direction gradually increases away from the guide member.

[0083] In this embodiment, the thickness dimension of the water stop 214 in the first direction gradually decreases away from the guide member along the third direction, and the thickness dimension of the extrusion member 215 in the first direction gradually increases away from the guide member along the third direction. For example, in the first direction, the side surface of the extrusion member 215 facing the water stop 214 can be a slope, and the side surface of the water stop 214 facing the extrusion member 215 can be a slope. When the sliding portion of the guide seat 216 of the cleaning mechanism 20 disengages from the adjusting groove 401 and moves to abut against the side wall of the mounting groove 411, the water stop 214 moves away from the adjusting groove 401 relative to the extrusion member 215 along the third direction. Since the limiting member 224 limits the guide seat 216 in the first direction, the water stop 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 stop 214 can more stably and reliably block the water outlet 2121 of the water storage member 212.

[0084] In one example of the present invention, reference Figure 7 、 Figure 8 and Figure 10 As shown, the cleaning mechanism 20 may further include: a support plate 217 and a second elastic member 222 , a scraper 219 and a positioning plate 218 and a third elastic member 223 .

[0085] Specifically, the length direction of the support plate 217 is in the same direction as the third direction, the thickness direction of the support plate 217 is in the same direction as the first direction, the support plate 217 is arranged between the water storage part 212 and the cleaning cotton 213 and is connected to the cleaning cotton 213, the second elastic member 222 is arranged between the support plate 217 and the water storage part 212, and the second elastic member 222 can be elastically deformed along the first direction; the length direction of the positioning plate 218 is in the same direction as the third direction, the thickness direction of the positioning plate 218 is in the same direction as the second direction, and the positioning plate 218 is arranged 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 arranged 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 and obliquely away from the water storage part 212 in a first direction, wherein, in the first direction, the other end of the scraper 219 exceeds the cleaning cotton 213; the third elastic member 223 can be elastically deformed along the second direction, and 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.

[0086] 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 arranged between the water storage part 212 and the cleaning cotton 213 and is connected to the cleaning cotton 213. The second elastic member 222 is arranged between the support plate 217 and the water storage part 212 and can be elastically deformed along the first direction. The structure is simple, and the cleaning cotton 213 can be well supported and buffered in the first direction. When the cleaning mechanism 20 moves 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, it stably and reliably contacts the display panel 421 and forms a stable abutment and pressure, so that the cleaning cotton 213 can clean the dirt on the display panel 421 well as the movement of the cleaning mechanism 20. The setting of the second elastic member 222 can make the cleaning cotton 213 well adapt to the surface undulations and surface drop 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.

[0087] In this embodiment, the cleaning mechanism 20 also includes a scraper 219 and a positioning plate 218. The positioning plate 218 is arranged 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 cooperate with the sliding frame 211 to play a good role in limiting and fixing the cleaning cotton 213 and the support plate 217, reducing the movement of the support plate 217 and the cleaning cotton 213 in the second direction, so that the support plate 217 and the cleaning cotton 213 can move more stably along the first direction to perform cleaning operations.

[0088] The scraper 219 is arranged on the side of the positioning plate 218 away from the support plate 217, and the arrangement is reasonable. One end of the scraper 219 is rotatably connected to the sliding frame 211, and the other end of the scraper 219 extends upwardly and obliquely away from the water storage part 212 in a first direction. The scraper 219 is connected to the top wall of the sliding frame 211 through a third elastic member 223. The structure is simple. In the process of the cleaning mechanism 20 moving from top to bottom, the cleaning cotton 213 cooperates with the input cleaning liquid to clean the display panel 421, so that there will be more liquid beads on the display panel 421 after cleaning, which interferes with the operator's viewing of the information displayed on the display panel 421. The scraper 219 is arranged on the upper side of the cleaning cotton 213, and can scrape off the liquid beads on the display panel 421 after the cleaning cotton 213 is cleaned, thereby reducing the residual liquid beads and facilitating the display The use of panel 421, for example, during the movement of the cleaning mechanism 20 along the second direction, the scraper 219 can cooperate well with the ups and downs and differences in the bottom wall surface of the display panel 421 and the mounting groove 411 in the first direction through the compression and stretching of the third elastic member 223, so that the other end of the scraper 219 can always be stably and reliably abutted against the display panel 421 under the action of the third elastic member 223 to perform scraping operations. The other end of the scraper 219 extends upward at an angle, which can facilitate the scraper 219 to rotate around the rotation axis of one end thereof, so that the scraper 219 can stably abut against the display panel 421. The other end of the scraper 219 can be formed with an inclined surface that cooperates with the display panel 421 to increase the contact area with the display panel 421 and reduce the probability of the scraper 219 scratching and damaging the display panel 421.

[0089] When the cleaning mechanism 20 moves from bottom to top, the positioning plate 218 can limit the rotation of the scraper 219 to a certain extent, so that the scraper 219 can rotate within a more appropriate range, thereby making the operation of the scraper 219 more stable.

[0090] In some specific embodiments of the present invention, reference Figure 5 and Figure 6As shown, the cleaning mechanism 20 also includes a cleaning roller 225, which extends along the third direction. The cleaning roller 225 is arranged on the lower side of the display panel 421, and 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 arranged in the cleaning groove, and in the first direction, part of the cleaning roller 225 protrudes from the opening of the cleaning groove. The cleaning roller 225 is used to remove sewage at the scraper 219.

[0091] In this embodiment, the cleaning mechanism 20 also includes a cleaning roller 225. The cleaning roller 225 is arranged on the lower side of the display panel 421 and is 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 the sewage at the scraper 219. The arrangement is reasonable. In the process of the cleaning mechanism 20 cleaning the display panel 421 from top to bottom, the liquid droplets remaining on the display panel 421 gradually gather to 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.

[0092] Exemplarily, the cleaning roller 225 can be a cotton roller so that the sewage can be adsorbed onto the cleaning roller 225. The cleaning roller 225 is rotatably arranged in the cleaning groove and partially protrudes from the opening of the cleaning groove. Then, 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 to pass over the cleaning roller 225 through the compression of the second elastic member 222 at the cleaning roller 225. During the process of the cleaning cotton 213 passing through the cleaning roller 225, the water generated by the squeezing of the cleaning cotton 213 can be adsorbed 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 is squeezed and rotated 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 an extruded state 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 avoid the scraper 219 and the cleaning roller 225 from getting stuck when the cleaning mechanism 20 moves from bottom to top, so that the scraper 219 can be smoothly separated from the cleaning roller 225, thereby making the operation of the cleaning component 100 more stable.

[0093] In a specific embodiment of the present invention, the cleaning roller 225 is detachably mounted in the cleaning tank, which facilitates the disassembly and assembly of the cleaning roller 225 and enables the cleaning roller 225 to be conveniently removed from the cleaning tank for cleaning or replacement when cleaning is required.

[0094] In some embodiments of the present invention, reference Figure 11 As shown, hydrogen power generation equipment 400 may further include: a hydrogen storage tank, a hydrogen power generation unit, a hydrogen storage device, and a delivery pipeline. The hydrogen storage tank, hydrogen power generation unit, hydrogen storage device, and delivery pipeline are all located within housing 410. 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 the pipeline connection; the temperature sensor 424 is distributed and installed on the hydrogen power generation unit; the pressure sensor 425 is installed on the hydrogen storage device and the delivery pipeline; and the alarm device 422 is installed in housing 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 through the controller. This can meet the operational requirements of hydrogen power generation equipment 400.

[0095] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the hydrogen power generation equipment 400 installation monitoring device can also include a support rod 300, which is retractable. There are two support rods 300, and the two support rods 300 are arranged at intervals in the third direction.
