[0014] In some embodiments, the support frame comprises a first support frame and a second support frame, the first support frame and the second support frame are alternately connected between two adjacent columns.

[0015] The telescopic part is connected to the first support frame, and when the telescopic part is in the retracted state, the two long edges of the explosion-proof plate are in close contact with the second support frame.

[0016] In some embodiments, the explosion-proof plate has a V-shaped plate surface.

[0017] The telescopic part is connected to one side of the groove of the V-shaped plate surface, and the parts where the two long edges of the explosion-proof plate are in close contact with the second support frame are symmetrically arranged about the telescopic part.

[0018] In some embodiments, the rack pipe slot comprises a mounting port and a clamping port connected in communication.

[0019] The clamping port is located below the mounting port, and the caliber of the clamping port is smaller than the caliber of the mounting port.

[0020] In some embodiments, the rear wall is provided with an operation port and a plurality of rack pipe slots.

[0021] The plurality of rack pipe slots are arranged side by side on the rear wall, and the operation port is arranged above and / or below the rack pipe slots.

[0022] In some embodiments, the rear wall is further provided with an instrument slot.

[0023] The instrument slot is arranged near the rack pipe slot for installing a gas pressure detector.

[0024] In some embodiments, the hydrogen long pipe trailer loading and unloading platform further comprises a gas detector.

[0025] The gas detector is installed on the roof, and the gas detector is located in the parking area and near the rear wall.

[0026] In some embodiments, the hydrogen long pipe trailer loading and unloading platform further comprises a bottom plate arranged at the bottom of the side wall and the rear wall.

At the same time, the connecting pipe on the hydrogen compressor can pass through the pipe slot into the parking area and be connected with the hydrogen cylinder on the long tube trailer to fill hydrogen. During the filling process, since the side wall, the rear wall and the ceiling surround a relatively closed parking area space, if there is a hydrogen leakage at the connection part of the connecting pipe and the long tube trailer, the leaked hydrogen can be gathered in the parking area. In this way, the hydrogen in the parking area can be detected by the detection instrument, so as to determine whether there is a hydrogen leakage in the long tube trailer during the filling process.

[0030] Of course, when the hydrogen unloading operation is performed, the loading and unloading platform can also make the leaked hydrogen gather in the parking area, so as to determine whether there is a hydrogen leakage in the long tube trailer during the unloading process by the detection result of the detection instrument. The present disclosure can collect the leaked hydrogen by setting the loading and unloading platform at the loading and unloading position of the long tube trailer, so that the operating personnel can timely find, adjust and handle the leaked hydrogen, thereby reducing the safety hidden danger in the station, improving the safety coefficient of the operation in the station, and reducing the loss of hydrogen. In addition, after the long tube trailer finishes loading and unloading hydrogen, the hydrogen in the parking area can also be discharged out of the parking area through the entrance, so that the subsequent long tube trailer can continue the loading and unloading operation of hydrogen.

[0031] Other features and advantages of the present disclosure will be described in detail in the following specific embodiments. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0042] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0043] In the present disclosure, the orientation words used are defined based on the plane direction shown in the drawings, which are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, and a particular orientation configuration and operation, and therefore cannot be understood as a limitation on the present disclosure. The terms "inner" and "outer" refer to the inner and outer of the corresponding structure profile.

[0044] In addition, it should be noted that the terms such as "first", "second" and the like are used only to distinguish one element from another element, and do not have sequential or important meanings. In addition, in the description with reference to the drawings, the same reference signs in different drawings represent the same elements.

[0045] In the description of the present disclosure, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected", "linked", "mounted" should be understood broadly, for example, can be fixedly connected, or can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances.

[0046] The present disclosure provides a hydrogen long tube trailer loading and unloading platform 01, as shown in the accompanying drawings, for assisting the loading and unloading of hydrogen by a long tube trailer. The hydrogen long tube trailer loading and unloading platform 01 can include side walls 10, a rear wall 20, and a roof 30. The two side walls 10 can be oppositely arranged, and the rear wall 20 is connected to the two side walls 10. The rear wall 20 can be provided with a pipe rack groove 21 for mounting a connecting pipe 021. The roof 30 is connected to the top of the rear wall 20 and the two side walls 10. The roof 30, the rear wall 20, and the two side walls 10 can enclose a parking area 40 with an entrance. The long tube trailer can enter the parking area 40 through the entrance and load and unload hydrogen through the connecting pipe 021. Figures 1 to 7

[0047] It should be noted that, in some embodiments, the hydrogen long tube trailer can be filled with hydrogen using a hydrogen compressor 02 as shown in the accompanying drawings. In other embodiments, the long tube trailer can be unloaded with hydrogen using a hydrogen unloading column (not shown in the drawings). In order to better demonstrate the content of the present disclosure, the following examples will be described by taking the hydrogen filling of the long tube trailer as an example, but the hydrogen long tube trailer loading and unloading platform 01 provided by the present disclosure is not limited to the hydrogen filling operation of the long tube trailer, and is also applicable to the hydrogen unloading operation of the long tube trailer. Figure 4

[0048] Through the above technical solution, when the hydrogen filling operation is performed, the long tube trailer can enter the parking area 40 through the entrance of the parking area 40. At the same time, the connecting pipe 021 on the hydrogen compressor 02 can pass through the pipe rack groove 21 into the parking area 40 and be connected to the hydrogen cylinder on the long tube trailer to fill hydrogen. During the filling process, since the side walls 10, the rear wall 20, and the roof 30 enclose a relatively closed parking area 40 space, if there is a hydrogen leakage at the connection between the connecting pipe 021 and the long tube trailer, the leaked hydrogen can be collected in the parking area 40. In this way, the hydrogen in the parking area 40 can be detected by a detection instrument, so as to determine whether there is a hydrogen leakage during the filling of the long tube trailer.

[0049] Of course, when the hydrogen unloading operation is performed, the loading and unloading platform can also cause the leaked hydrogen to collect in the parking area 40, so as to determine whether there is a hydrogen leakage during the unloading of the long tube trailer through the detection result of the detection instrument. The present disclosure can collect the leaked hydrogen by arranging the loading and unloading platform at the loading and unloading position of the long tube trailer, so that the operating personnel can timely find, adjust, and handle the leaked hydrogen, thereby reducing the safety hidden danger in the station, improving the safety factor of the operation in the station, and reducing the loss of hydrogen. In addition, after the loading and unloading of hydrogen by the long tube trailer is completed, the hydrogen in the parking area 40 can also be discharged out of the parking area 40 through the entrance, so that the subsequent long tube trailer can continue the loading and unloading operation of hydrogen. ​​

[0050] In some embodiments, as shown in FIG. 1, the side wall 10 can include a column 11, a support frame 12 and a blast-proof plate 13. A plurality of support frames 12 can be connected between two adjacent columns 11, and the blast-proof plates 13 can be connected on the support frames 12. The blast-proof plates 13 can have gaps 14 between two adjacent blast-proof plates 13. The column 11 and the support frame 12 can be made of a type of steel to ensure the structural strength of the side wall 10. The blast-proof plate 13 can be made of a type of blast-proof glass to facilitate the observation of the working condition in the parking area 40 by the workers. The support frame 12 can be connected with the column 11 by welding, screwing or riveting. The specific material of the column 11, the support frame 12 and the blast-proof plate 13 and the connection mode between the support frame 12 and the column 11 are not specially limited in the present disclosure. Figure 2 Figure 3 In this way, the column 11 and the support frame 12 can form the framework of the side wall 10, and the blast-proof plate 13 arranged on the support frame 12 can block and retard the leakage of hydrogen gas to a certain extent in the extreme state, so as to reduce the secondary danger caused by the diffusion of the explosive, thereby minimizing the loss. When there is a small amount of hydrogen gas leakage in the parking area 40, the gaps 14 between the adjacent blast-proof plates 13 can make a small amount of hydrogen gas discharge out of the parking area 40, so as to avoid the risk caused by the excessive concentration of the hydrogen gas. When there is a large amount of hydrogen gas leakage in the parking area 40, the blast-proof plate 13 can block and retard the leakage of hydrogen gas, so that the workers can detect the leakage of hydrogen gas through the detection equipment. Meanwhile, the leaked hydrogen gas can also discharge out of the parking area 40 through the gaps 14 between the blast-proof plates 13 after the loading and unloading of hydrogen gas in the long tube trailer is completed.

[0051] Of course, a blower or an air extractor can be used to assist the exhaust of hydrogen gas when discharging the hydrogen gas. In addition, since the hydrogen gas will flow to the ceiling 30 after the leakage, the discharge of hydrogen gas can also be controlled by arranging the on-off valves on the ceiling 30. The specific device and structure for discharging hydrogen gas in the parking area 40 are not specially limited in the present disclosure.

[0052] Meanwhile, if it is necessary to quickly discharge the hydrogen gas to avoid the accumulation of hydrogen gas, a larger area and density of gaps 14 can be arranged on the side wall 10. If it is necessary to slowly discharge the hydrogen gas to better detect whether the hydrogen gas is leaking, a smaller area and density of gaps 14 can be arranged on the side wall 10. It can be understood that the area and density of the gaps 14 arranged along the height direction of the side wall 10 can also be different. The specific way of arranging the gaps 14 on the side wall 10 is not specially limited in the present disclosure.

[0053] On this basis, as shown in FIG. 2, the side wall 10 can include a column 11, a support frame 12 and a blast-proof plate 13. A plurality of support frames 12 can be connected between two adjacent columns 11, and the blast-proof plates 13 can be connected on the support frames 12. The blast-proof plates 13 can have gaps 14 between two adjacent blast-proof plates 13. The column 11 and the support frame 12 can be made of a type of steel to ensure the structural strength of the side wall 10. The blast-proof plate 13 can be made of a type of blast-proof glass to facilitate the observation of the working condition in the parking area 40 by the workers. The support frame 12 can be connected with the column 11 by welding, screwing or riveting. The specific material of the column 11, the support frame 12 and the blast-proof plate 13 and the connection mode between the support frame 12 and the column 11 are not specially limited in the present disclosure.

[0054] In this way, the column 11 and the support frame 12 can form the framework of the side wall 10, and the blast-proof plate 13 arranged on the support frame 12 can block and retard the leakage of hydrogen gas to a certain extent in the extreme state, so as to reduce the secondary danger caused by the diffusion of the explosive, thereby minimizing the loss. When there is a small amount of hydrogen gas leakage in the parking area 40, the gaps 14 between the adjacent blast-proof plates 13 can make a small amount of hydrogen gas discharge out of the parking area 40, so as to avoid the risk caused by the excessive concentration of the hydrogen gas. When there is a large amount of hydrogen gas leakage in the parking area 40, the blast-proof plate 13 can block and retard the leakage of hydrogen gas, so that the workers can detect the leakage of hydrogen gas through the detection equipment. Meanwhile, the leaked hydrogen gas can also discharge out of the parking area 40 through the gaps 14 between the blast-proof plates 13 after the loading and unloading of hydrogen gas in the long tube trailer is completed. Figure 3 ​As shown, the side wall 10 can further include a telescopic member 15 and an elastic member 16. The telescopic member 15 is connected between the support frame 12 and the explosion-proof plate 13, and the elastic member 16 can be sleeved on the telescopic member 15 and arranged between the support frame 12 and the explosion-proof plate 13. The telescopic member 15 can be selected from a linear bearing, a telescopic sleeve or a slide rod assembly, and the elastic member 16 can be selected from a spring, a spring piece or a disc spring. The elastic member 16 can be assembled inside or outside the telescopic member 15. The specific structure of the telescopic member 15 and the elastic member 16 and the specific position of the elastic member 16 are not limited in particular.

[0055] In a normal state, the explosion-proof plate 13 is pushed open under the elastic action of the elastic member 16. When the hydrogen gas explodes in an extreme state, the impact force of the explosion causes the explosion-proof plate 13 to move towards the support frame 12 and adhere to the support frame 12, thereby buffering the impact force of the explosion to reduce the loss and personnel injury in the extreme case. In this way, the telescopic member 15 and the elastic member 16 can constitute the first buffering mechanism of the explosion impact force.

[0056] In addition, as shown in Figure 3 The support frame 12 can include a first support frame 121 and a second support frame 122, and the first support frame 121 and the second support frame 122 are alternately connected between two adjacent vertical columns 11. The telescopic member 15 is connected to the first support frame 121, and when the telescopic member 15 is in a retracted state, the two long edges of the explosion-proof plate 13 can adhere to the second support frame 122. The first support frame 121 and the second support frame 122 can be alternately arranged, that is, the support frame 12 connected with the telescopic member 15 and the support frame 12 not connected with the telescopic member 15 can be distributed alternately on the side wall 10.

[0057] In this way, the two sides of the explosion-proof plate 13 can adhere to the second support frame 122 under the action of the explosion impact force to form a closed side wall 10, so that the explosion-proof plate 13 and the support frame 12 can jointly resist the impact force of the explosion, thereby enhancing the impact resistance strength of the side wall 10. In addition, the closed side wall 10 formed by the adhesion of the explosion-proof plate 13 and the support frame 12 can also block and retard the explosion of hydrogen gas.

[0058] In some embodiments, as shown in Figure 3 The explosion-proof plate 13 can have a V-shaped plate surface 131. The telescopic member 15 can be connected to one side of the groove of the V-shaped plate surface 131, and the positions where the two long edges of the explosion-proof plate 13 adhere to the second support frame 122 can be symmetrically arranged about the telescopic member 15.

[0059] In this way, when the explosion-proof plate 13 is attached to the second support frame 122, the second support frame 122 can support both sides of the explosion-proof plate 13. Since the explosion-proof plate 13 is provided in a V-shaped structure, under the impact of the explosion, the V-shaped plate surface of the explosion-proof plate 13 has a tendency to flatten, but the raised V-shaped plate surface has a force resisting flattening deformation, thereby buffering the impact of the explosion to form a second buffer mechanism for the explosion impact. The positions where the two long edges of the explosion-proof plate 13 are attached to the second support frame 122 are symmetrically arranged about the telescopic member 15, so that the support forces on both sides of the explosion-proof plate 13 are the same, thereby avoiding the situation that one side of the explosion-proof plate 13 is damaged before the other side. Of course, the explosion-proof plate 13 can also be provided in an arc-shaped plate structure, and the specific structure of the explosion-proof plate 13 is not specially limited in the present disclosure.

[0060] The present disclosure can provide good buffering effect for the explosion of hydrogen gas in extreme cases through the first buffer mechanism and the second buffer mechanism, so as to consume part of the impact force, thereby reducing the damage caused by the explosion impact to the remaining equipment and personnel in the station. In the normal use state, the present disclosure can also collect the leaked hydrogen gas, so that the operating personnel can detect whether there is leakage when the long tube trailer is loading or unloading hydrogen gas, so that the operating personnel can take measures to handle the hydrogen gas leakage in time.

[0061] The above embodiment is a detailed introduction to the structure of the side wall 10 of the hydrogen long tube trailer loading and unloading platform 01. In order to better show the content of the present disclosure, the following embodiment will make a detailed description of the rear wall 20 of the hydrogen long tube trailer loading and unloading platform 01. As shown in Figure 4 and Figure 5 The pipe mounting groove 21 can include an installation port 211 and a clamping port 212 connected thereto. The clamping port 212 is located below the installation port 211, and the caliber of the clamping port 212 is smaller than that of the installation port 211.

[0062] When the hydrogen compressor 02 is used to charge the long tube trailer, as shown in Figure 6 and Figure 7 Since the caliber of the clamping port 212 is smaller than that of the installation port 211, the connecting pipe 021 on the hydrogen compressor 02 can pass through the installation port 211 into the parking area 40 to be connected to the hydrogen cylinder on the long tube trailer. During hydrogen charging, the pipe wall of the connecting pipe 021 can be clamped in the clamping port 212, so that the connecting pipe 021 remains in a fixed position, thereby improving the stability of the connecting pipe 021 during charging and avoiding the problem of hydrogen leakage due to inclination or shaking of the connecting pipe 021.

[0063] In some embodiments, as shown in Figure 4 and Figure 5As shown, the rear wall 20 can also be provided with an operation opening 22 and a plurality of pipe rack slots 21. The plurality of pipe rack slots 21 can be arranged side by side on the rear wall 20, and the operation opening 22 can be arranged above and / or below the pipe rack slots 21. That is, the operation opening 22 can be arranged above the pipe rack slots 21, below the pipe rack slots 21, or both above and below the pipe rack slots 21.

[0064] When loading or unloading hydrogen, the operator does not need to enter the parking area 40, but only needs to operate and adjust the connecting pipe 021 outside the rear wall 20 through the operation opening 22, thereby ensuring the safety of personnel operation. In addition, the plurality of pipe rack slots 21 arranged on the rear wall 20 allows the connecting pipe 021 to be connected to the hydrogen cylinder of the long pipe trailer in different postures, which facilitates the adjustment of different positions of the connecting pipe 021 during connection, thereby reducing the problem of hydrogen leakage caused by the inclined connection position of the connecting pipe 021. Of course, the plurality of pipe rack slots 21 can be arranged side by side on the rear wall 20 or in a quincunx shape on the rear wall 20. The present disclosure does not specially limit the specific distribution shape of the plurality of pipe rack slots 21 arranged on the rear wall 20.

[0065] In addition, as shown in Figure 5 , the rear wall 20 can also be provided with an instrument slot 23. The instrument slot 23 can be arranged near the pipe rack slot 21 for installing a gas pressure detector 03. The gas pressure detector 03 can be connected to the output port of the hydrogen compressor 02, and when the gas pressure detector 03 detects that the gas pressure value is greater than 20 MPa, it indicates that the hydrogen gas pressure inside the long pipe trailer is greater than 20 MPa. At this time, the gas pressure detector 03 can issue an alarm and stop the hydrogen compressor 02 through the control device. The present disclosure does not specially limit the specific position of the instrument slot 23.

[0066] In order to better detect the leaked hydrogen in the parking area 40, as shown in Figure 1 and Figure 4 , the hydrogen long pipe trailer loading and unloading platform 01 can also include a gas detector 31. The gas detector 31 can be installed on the roof 30, and the gas detector 31 is located inside the parking area 40 and close to the rear wall 20. Among them, the gas detector 31 can be selected from catalytic type or infrared optical type combustible gas detector. The present disclosure does not specially limit the specific type of gas detector 31.

[0067] Since the connecting part of the adapter pipe 021 and the hydrogen cylinder is close to the rear wall 20, and the hydrogen continuously flows to the ceiling 30 after the leakage, the gas detector 31 is arranged in the parking area 40 and close to the rear wall 20, so that the gas detector 31 can more easily detect whether there is a hydrogen leakage problem during the loading and unloading operation of the long tube trailer. Of course, the gas detector 31 can also be arranged on the rear wall 20 or the side wall 10. In addition, a plurality of gas detectors 31 can also be arranged in the parking area 40, and the plurality of gas detectors 31 can be arranged on the side wall 10, the rear wall 20 and the ceiling 30 respectively. The specific number and position of the gas detector 31 are not specially limited in the present disclosure.

[0068] In addition, as shown in Figure 1 and Figure 2 The hydrogen long tube trailer loading and unloading platform 01 can also include a bottom plate 50 arranged at the bottom of the side wall 10 and the rear wall 20. The bottom plate 50 can be provided with a wheel groove 51, and a wheel stop 52 can be arranged in the wheel groove 51. The long tube trailer can enter the parking area 40 through the wheel groove 51 and stop at the position of the wheel stop 52. The wheel stop 52 can be selected from a wheel lock, a wheel stop rod or a wheel groove structure. The wheel stop 52 can be arranged at the entrance of the parking area 40 or close to the rear wall 20. The specific structure and arrangement position of the wheel stop 52 are not specially limited in the present disclosure.

[0069] In this way, the long tube trailer can be parked in the parking area 40 through the wheel groove 51 and the wheel stop 52, so that the distance between the interface at the tail of the long tube trailer and the rear wall 20 is fixed and adapted, so that the adapter pipe 021 can be connected to the hydrogen cylinder to complete the loading and unloading operation of the hydrogen. The side wall 10 can be arranged to different lengths, so that the long tube trailer can be partially or completely parked in the parking area 40. At this time, the wheel groove 51 can be partially or completely located in the parking area 40. The specific length of the wheel groove 51 is not specially limited in the present disclosure.

[0070] The hydrogen long tube trailer loading and unloading platform 01 provided by the present disclosure can collect hydrogen leaked by the long tube trailer during loading and unloading operation by setting the side wall 10, the rear wall 20 and the ceiling 30, so that the operator can detect and take corresponding measures in time and quickly to reduce the risk of operation. At the same time, the gap 14 between the explosion-proof plates 13 can discharge a small amount of leaked hydrogen, and the explosion-proof plates 13 can also block and delay the leakage of hydrogen when a large amount of hydrogen leaks. In the case of explosion, the first and second buffer mechanisms can also consume part of the impact force, thereby reducing the damage to the remaining equipment and personnel in the station caused by the impact force of the explosion. During the loading and unloading of hydrogen, the hydrogen long tube trailer loading and unloading platform 01 can also clamp and fix the connecting pipe 021 of the hydrogen compressor 02 through the pipe slot 21, so as to avoid the leakage of hydrogen caused by the shaking of the connecting pipe 021. In summary, the hydrogen long tube trailer loading and unloading platform 01 provided by the present disclosure is beneficial to timely eliminate the safety hazards during operation and reduce the loss of high-pressure hydrogen.

[0071] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above-described embodiments. Within the technical concept range of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection range of the present disclosure.

[0072] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combination manners.

[0073] In addition, various different embodiments of the present disclosure can also be combined in any manner, as long as they do not deviate from the idea of the present disclosure, and they should also be considered as disclosed by the present disclosure.
