Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of prefabricated cabins, and specifically, to a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board. Background Art

[0002] In the fields of electric power, communication, etc., prefabricated cabins, as an integrated equipment installation and operation platform, have been widely used. Prefabricated cabins are usually used to accommodate various electrical equipment, such as transformers, distribution cabinets, communication equipment, etc., providing a stable operating environment for these equipment. With the development of society, higher requirements have been put forward for the safety, reliability, etc. of prefabricated cabins. In the process of using existing prefabricated cabins, there is a relatively prominent problem, that is, the lack of effective anti-theft measures. At present, most prefabricated cabins are mainly protected by simple first door locks and other methods. This protection method often fails to play an effective blocking role when facing the theft behavior of some lawbreakers. Since the electrical equipment placed in the prefabricated cabin usually has a high value, once a theft occurs, it will not only cause economic losses to the equipment owner, but also may affect the normal operation of power, communication and other systems, causing a greater range of adverse effects. Summary of the Invention

[0003] To overcome the above defects, embodiments of the present invention provide a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board, which solves the technical problem in the prior art that the electrical equipment placed in the prefabricated cabin is easily lost due to the lack of anti-theft measures in the prefabricated cabin.

[0005] For example, in a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board provided by at least one embodiment of the present invention, the anti-theft unit further includes: A first rotating member that can rotate on the cabin door around an axis parallel to the cabin door, and the second door lock is installed on the side wall of the first rotating member; A traction rope, with both ends of the traction rope respectively connected to the first rotating member and the baffle. The first rotating member can wind the traction rope on the side wall of the first rotating member when rotating, and drive the baffle to slide through the traction rope.

[0006] For example, in a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board provided by at least one embodiment of the present invention, the first rotating member is a cylinder, and the anti-theft unit further includes: A third rotating member that is rotatably arranged on the cabin door, and the axis of rotation has an included angle with the axis of the first rotating member. The first rotating member is rotatably connected to the side of the third rotating member close to the outer wall of the cabin door; the third rotating member can drive the first rotating member to rotate when rotating, so as to change the axis orientation of the first rotating member.

[0007] For example, in a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board provided by at least one embodiment of the present invention, the first rotating member is a sphere, and the anti-theft unit further includes: A second rotating member that is rotatably arranged on the cabin door, and the first rotating member is ball-jointed to the side of the second rotating member close to the outer wall of the cabin door; the second rotating member can drive the first rotating member to rotate when rotating, so as to change the axis orientation of the first rotating member; After the second rotating member rotates along the axis perpendicular to the outer wall of the cabin door, the first rotating member can rotate in the opposite direction along the same axis, so that the direction and position of the second lock hole remain unchanged.

[0008] For example, in a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board provided by at least one embodiment of the present invention, a plurality of guiding grooves are circumferentially formed on the spherical surface of the first rotating member around the direction perpendicular to the outer wall of the cabin door; a limiting rod is slidably and penetratingly connected to the second rotating member; the limiting rod can slide into the guiding groove, so that the first rotating member can only rotate around an axis parallel to the outer wall of the cabin door.

[0009] For example, in a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board provided by at least one embodiment of the present invention, a first elastic member is provided between the limiting rod and the second rotating member, and the first elastic member is used to provide the force for the limiting rod to enter the guiding groove.

[0010] For example, in a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board provided by at least one embodiment of the present invention, one side of the first rotating member exposed outside the cabin door wall has a pushing portion, and the pushing portion is used to contact and then push the first rotating member to rotate.

[0011] For example, in a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board provided by at least one embodiment of the present invention, a plurality of locking holes are circumferentially formed on the side wall of the second rotating member, and positioning holes corresponding to the locking holes are circumferentially formed on the inner wall of the cabin door; the locking holes and the positioning holes are penetrated by fasteners to limit the position of the second rotating member relative to the cabin door.

[0012] For example, in a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board provided by at least one embodiment of the present invention, a sliding groove is formed on the outer wall of the cabin door, the baffle slides in the sliding groove, and a second elastic member is further provided in the sliding groove. Both ends of the second elastic member act on the inner wall of the sliding groove and the side wall of the baffle respectively, and are used to provide a force for the baffle to slide close to the first locking hole, so that the baffle blocks the first locking hole.

[0013] For example, in a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board provided by at least one embodiment of the present invention, the number of the pushing portions is several, and they are circumferentially distributed around the direction perpendicular to the outer wall of the cabin door on one side of the first rotating member exposed outside the cabin door wall.

[0014] The beneficial effects of the embodiments of the present invention are as follows: In the present invention, by blocking the first locking hole with the baffle, the unconventional operation is guided to the second door lock provided with an alarm mechanism, and the rotation of the second door lock triggers the induction alarm, combining physical protection with electronic alarm. The sliding function of the baffle provides an unlocking condition during normal operation and automatically maintains the protection state in the non-operation state. The cooperation between the second door lock and the induction alarm warns against unconventional attempts. Compared with the single door lock protection in the prior art, a hierarchical anti-theft system is constructed, improving the safety performance of the prefabricated cabin.

Detailed implementation manners The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention.

In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0019] In this text, it should be noted that unless otherwise clearly stipulated and defined, the terms "install", "connect", and "join" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components.

[0020] In the present invention, unless otherwise clearly stipulated and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween.

[0022] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0023] As Figures 1 - 2 shown, it shows a composite prefabricated cabin based on a non-metallic high-strength fiber fireproof board in an embodiment of the present invention. A hatch 11 is opened on the side wall of the cabin body 1. The side wall of the hatch 11 is connected to the cabin door 12 through a rotational connection structure. After the cabin door 12 rotates, it can close the hatch 11. The first door lock 2 is arranged on the cabin door 12 and has a first keyhole 21 exposed on the outer wall of the cabin door 12. When the cabin door 12 closes the hatch 11, by inserting a key into the first keyhole 21 and rotating the first door lock 2, the position locking of the cabin door 12 relative to the cabin body 1 can be restricted or released. A baffle 3 is slidably connected to the outer wall of the cabin door 12. The sliding path of the baffle 3 covers the first keyhole 21, and the first keyhole 21 is blocked by the baffle 3 in the natural state.

[0024] The anti-theft unit 4 includes a second door lock 41 and an induction alarm arranged on the hatch door 12. The second door lock 41 has a second keyhole 411 exposed on the outer wall of the hatch door 12. The induction alarm is arranged inside the hatch door 12 and is inductively connected to the second door lock 41. When the second door lock 41 is triggered to rotate through the second keyhole 411, the induction alarm receives the trigger signal and starts to alarm.

[0025] In actual operation, to open the hatch door 12, the baffle 3 needs to be slid along a preset direction first to make the baffle 3 disengage from the area where the first keyhole 21 is located, exposing the first keyhole 21, and then the first door lock 2 is rotated by a key to unlock; when a non-staff member does not slide the baffle 3, the first keyhole 21 is in a blocked state. If an attempt is made to rotate the second door lock 41 through the second keyhole 411, the induction alarm will immediately respond and give an alarm.

[0026] The rotational connection structure between the cabin body 1 and the hatch door 12 realizes the closable function of the hatch 11. The first door lock 2 forms a lock through the triggering mechanism of the first keyhole 21. The sliding setting of the baffle 3 blocks the first keyhole 21 in the natural state, constituting physical protection for the first door lock 2. The inductive connection between the second door lock 41 and the induction alarm in the anti-theft unit 4 forms an alarm triggering mechanism. When the second door lock 41 is rotated abnormally, the induction alarm immediately alarms to monitor potential intrusion behaviors.

[0027] By blocking the first keyhole 21 with the baffle 3, unconventional operations are guided to the second door lock 41 provided with an alarm mechanism. The rotation of the second door lock 41 triggers the induction alarm, combining physical protection with electronic alarm. The sliding function of the baffle 3 provides unlocking conditions during normal operation and automatically maintains a protective state in the non-operating state. The cooperation between the second door lock 41 and the induction alarm warns against unconventional attempts. Compared with the single door lock protection in the prior art, a hierarchical anti-theft system is constructed, improving the safety performance of the prefabricated cabin.

[0028] As Figures 2 - 4 shown, the first rotating member 42 of the anti-theft unit 4 can rotate on the outer wall of the hatch door 12 (the rotation recorded here is multi-degree-of-freedom rotation, not limited to rotation in a certain fixed direction only). The second door lock 41 is fixedly installed on the side wall of the first rotating member 42, and the second keyhole 411 is exposed on the outer surface of the hatch door 12. One end of the traction rope 43 is wound and fixed on the outer peripheral surface of the first rotating member 42, and the other end passes through a guiding hole preset on the outer wall of the hatch door 12 and is connected to one side of the baffle 3 close to the first rotating member 42.

[0029] A sliding groove is provided on the outer wall of the hatch door 12 corresponding to the position of the first lock hole 21. The baffle 3 is embedded in the sliding groove and can slide horizontally along the groove body. In the natural state, when the first rotating member 42 is not subjected to an external force, the traction rope 43 is in a relaxed state, and the baffle 3 covers the first lock hole 21 under the action of gravity or a reset structure. When the staff needs to open the hatch door 12, the first rotating member 42 is directly manually rotated to rotate around its own axis. The traction rope 43 is tightened as the first rotating member 42 rotates, and then the baffle 3 is pulled to move along the sliding groove away from the first lock hole 21 until the first lock hole 21 is completely exposed. At this time, the first door lock 2 can be operated through the first lock hole 21 to unlock the hatch door 12. After the unlocking is completed, the first rotating member 42 is rotated in the reverse direction, the traction rope 43 is relaxed, and the baffle 3 returns to the initial position under the action of gravity or a reset structure to block the first lock hole 21.

[0030] The first rotating member 42 and the hatch door 12 form a rotating support structure. The winding connection between its outer peripheral surface and the traction rope 43 realizes the conversion of rotational motion into linear motion, so that the operation of rotating the first rotating member 42 can directly drive the baffle 3 to slide. This design provides an operation path independent of the second door lock 41 for the staff familiar with the alarm device: without triggering the second door lock 41 through the second lock hole 411, directly rotating the exposed first rotating member 42 can expose the first lock hole 21, simplifying the operation process during normal use.

[0031] The cooperation between the traction rope 43 and the sliding groove ensures the stability of the sliding trajectory of the baffle 3. Gravity or a reset structure enables the baffle 3 to automatically reset to block the first lock hole 21 in the non-operating state, maintaining the protection state of the first door lock 2. For non-staff members, because they do not understand the operation method of the first rotating member 42, if they try to pry the second door lock 41 through the second lock hole 411, the induction alarm will be triggered immediately, while the staff can avoid triggering the alarm by directly rotating the first rotating member 42, realizing an effective distinction in operation.

[0032] Such as Figure 6As shown, in this embodiment, the first rotating member 42 of the anti-theft unit 4 is a cylindrical member, which is rotatably connected to one side of the third rotating member 47 close to the outer wall of the hatch 12 through a horizontal rotating shaft, and its axis is parallel to the outer wall of the hatch 12. The third rotating member 47 is a disc-shaped member, which is rotatably arranged on the outer wall of the hatch 12 through a vertical rotating shaft. The second door lock 41 is fixedly installed on the side wall of the first rotating member 42, and the second lock hole 411 is exposed on the outer surface of the hatch 12. One end of the traction rope 43 is wound and fixed on the outer peripheral surface of the first rotating member 42, and the other end passes through the guiding hole on the outer wall of the hatch 12 and is connected to the baffle 3. When the third rotating member 47 rotates around the axis perpendicular to the outer wall of the hatch 12, it drives the first rotating member 42 to rotate synchronously, so that the rotating shaft of the first rotating member 42 parallel to the outer wall of the hatch 12 changes its orientation. For example, in the initial state, the rotating shaft of the first rotating member 42 is horizontal. After the third rotating member 47 rotates 90 degrees, the rotating shaft of the first rotating member 42 becomes vertical. At this time, the rotating direction of the first rotating member 42 changes from horizontal rotation to vertical rotation.

[0033] The two shafts of the first rotating member 42 and the third rotating member 47 are rotatably connected (the rotating shaft perpendicular to the outer wall of the hatch 12 and the rotating shaft parallel to the outer wall of the hatch 12), providing an additional degree of freedom of rotation for the first rotating member 42, so that the rotation axis of the first rotating member 42 can be adjusted relative to the outer wall of the hatch 12. This design avoids the problem that the operation rule is predictable due to the fixed rotation direction of the first rotating member 42. The operator can adjust the angle of the third rotating member 47 according to the preset security strategy, so that the rotation direction of the first rotating member 42 matches the sliding track of the baffle 3; because non-staff members do not know the correct angle of the third rotating member 47, even if they try to rotate the first rotating member 42, they will not be able to effectively drive the baffle 3 to move due to the rotation direction of the first rotating member 42 not matching the expectation, and a trigger induction alarm can also be set in the wrong rotation direction.

[0034] As Figure 5 shown, in another embodiment, the first rotating member 42 of the anti-theft unit 4 is a sphere, which is connected to one side of the second rotating member 44 close to the outer wall of the hatch 12 through a ball hinge structure, so that the sphere can rotate freely around the center of the ball. The second rotating member 44 is a circular ring-shaped member, which is rotatably arranged on the outer wall of the hatch 12 through a rotating shaft, and the axis of the rotating shaft is perpendicular to the outer wall of the hatch 12. The second door lock 41 is fixedly installed on the surface of the sphere. When the second rotating member 44 rotates clockwise around the axis perpendicular to the outer wall of the hatch 12, the sphere is controlled to rotate counterclockwise along the same axis through the linkage of the ball hinge structure, and the rotation angle is equal to the rotation angle of the second rotating member 44. This reverse rotation makes the shape of the second lock hole 411 on the sphere not shift back and forth.

[0035] The ball joint connection between the first rotating member 42 and the second rotating member 44 forms a reverse rotation mechanism. When the second rotating member 44 adjusts its angle, the sphere rotates in the opposite direction by the same angle, ensuring that the orientation of the second lock hole 411 remains unchanged.

[0036] Through the angle compensation mechanism of the ball joint connection, the rotation movement of the second rotating member 44 is converted into the reverse rotation of the sphere, ensuring that the direction and position of the second lock hole 411 are constant, eliminating the safety hazard caused by the skew of the lock hole. Non-staff members facing the second lock hole 411 that is always perpendicular to the outer wall of the hatch 12 cannot crack it by prying or rotating in a single direction, and the actual linkage trajectory is unpredictable due to the change in the rotation direction of the sphere, significantly improving the security and anti-cracking ability of the anti-theft unit 4.

[0037] As Figure 5 shown, the first rotating member 42 is a sphere, and its spherical surface is circumferentially and uniformly distributed with guiding grooves 421 around an axis perpendicular to the outer wall of the hatch 12. A limiting plane is provided at the bottom of the guiding groove 421. The second rotating member 44 is an annular member, rotatably arranged on the outer wall of the hatch 12, and the axis of the rotating shaft is perpendicular to the outer wall of the hatch 12. The limiting rod 45 penetrates through the second rotating member 44 and is reciprocally slidably connected thereto, and matches the size of the limiting plane of the guiding groove 421.

[0038] The first elastic member 46 is a tension spring, one end of which is connected to the second rotating member 44, and the other end is connected to the limiting rod 45. In the natural elongation state, the first elastic member 46 applies a force to the limiting rod 45 pointing to the guiding groove 421, causing the limiting rod 45 to enter the guiding groove 421. At this time, the rotational freedom of the first rotating member 42 is limited to only being able to rotate around an axis parallel to the outer wall of the hatch 12.

[0039] When it is necessary to adjust the first rotating member 42 to rotate around an axis perpendicular to the outer wall of the hatch 12, the limiting rod 45 is pulled in the direction away from the outer wall of the hatch 12. The first elastic member 46 is stretched and stores elastic potential energy, and the end of the limiting rod 45 disengages from the guiding groove 421. At this time, the first rotating member 42 can rotate around an axis perpendicular to the outer wall of the hatch 12. After adjusting to the target angle, the limiting rod 45 is released, and the first elastic member 46 resets and drives the limiting rod 45 to re-insert into the corresponding guiding groove 421, fitting with the guiding groove 421 at the new position, and restoring the restriction on the rotation of the first rotating member 42 around the parallel axis.

[0040] The connection structure between the first elastic member 46 and the limiting rod 45 enables the limiting rod 45 to always fit with the limiting plane of the guiding groove 421 under the action of elastic tension without external force, forming a passive mechanical limit, continuously restricting the rotation of the first rotating member 42 around an axis perpendicular to the outer wall of the hatch 12, and effectively resisting accidental rotation caused by external vibration or collision.

[0041] By combining elastic potential energy with mechanical limit, a controllable switching mechanism for the rotational degree of freedom is constructed: the elastic force ensures the limited state under normal conditions, the external force operation realizes temporary unlocking, and it automatically resets and locks after the operation is completed. This design avoids the accidental rotation of the first rotating member 42 caused by non-staff accidentally touching the second lock hole 411, and at the same time prevents the mechanism failure caused by external environmental interference.

[0042] As Figure 5 shown, several pushing parts 422 are provided on the end face of the first rotating member 42 exposed on the outer wall of the hatch door 12. When the hatch door 12 needs to be opened, an external force acts on the outer surface of the pushing part 422, which helps to push the first rotating member 42 to rotate around its axis.

[0043] The bump structure of the pushing part 422 provides a clear force application point for the first rotating member 42, enabling the operator to apply a rotational torque by directly contacting the pushing part 422, and the first rotating member 42 can be driven to rotate without the aid of other tools, simplifying the operation process during normal use.

[0044] As Figures 7 - 8 shown, the second rotating member 44 is rotatably arranged on the outer wall of the hatch door 12, and several locking holes 441 are evenly distributed along the circumferential direction on its side wall. In the installation area of the second rotating member 44 corresponding to the inner wall of the hatch door 12, positioning holes 13 are opened along the same circumferential direction, which match the number and position of the locking holes 441. The fastener is a bolt, and its length can penetrate through the locking hole 441 and the positioning hole 13 and cooperate with a nut.

[0045] When the angle of the second rotating member 44 needs to be fixed, rotate the second rotating member 44 to the target position, align a certain locking hole 441 with the positioning hole 13 on the inner wall of the hatch door 12, insert the bolt into the aligned hole and tighten the nut to realize the position locking of the second rotating member 44 relative to the hatch door 12. When the angle needs to be adjusted, loosen the nut, take out the bolt, rotate the second rotating member 44 to the new target position, and repeat the above steps to complete the re-fixation.

[0046] The locking holes 441 of the second rotating member 44 and the positioning holes 13 of the hatch door 12 are connected by fasteners to form an adjustable mechanical locking structure, ensuring that the second rotating member 44 remains fixed at the preset angle and preventing angle deviation caused by external force vibration or unconventional rotation. The circumferentially evenly distributed hole position design enables the second rotating member 44 to be locked at multiple angular positions, meeting the matching requirements of the first lock hole 21 and the sliding track of the baffle 3 under different layouts.

[0047] As Figure 9As shown in the figure, a rectangular chute 14 is provided on the outer wall of the hatch 12 corresponding to the position of the first lock hole 21. The length direction of the chute 14 is the same as the sliding direction of the baffle 3, and limiting convex edges are provided on both sides of the inner wall. The baffle 3 is a rectangular plate-shaped member, and grooves are formed on both sides thereof to cooperate with the limiting convex edges, and it is embedded in the chute 14 and can slide along the chute body. The second elastic member is a compression spring, one end of which is fixed to the inner wall of the chute 14 close to the edge of the hatch 12, and the other end is connected to the corresponding side wall of the baffle 3. In the natural state, it is in a compressed state and applies a thrust force to the baffle 3 along the length direction of the chute 14 and pointing to the first lock hole 21.

[0048] When the first door lock 2 needs to be operated, an external force overcomes the force of the second elastic member to slide the baffle 3 along the chute 14 in a direction away from the first lock hole 21 until the first lock hole 21 is completely exposed; after the operation is completed, the external force is removed, and the restoring force of the second elastic member pushes the baffle 3 to return to the initial position along the chute 14 to block the first lock hole 21. The limiting convex edges of the chute 14 cooperate with the grooves of the baffle 3 to limit the sliding track of the baffle 3 and prevent it from shifting or disengaging during the sliding process. The limiting cooperation structure between the chute 14 and the baffle 3, through the mechanical constraint of the convex edge and the groove, ensures that the baffle 3 slides stably along the preset direction and prevents the deviation of the sliding track caused by external force collision or vibration.

[0049] As Figure 2 As shown in the figure, the end face of the exposed end of the first rotating member 42 on the outer wall of the hatch 12 is circular, and six pushing parts 422 are evenly distributed circumferentially along the axis perpendicular to the outer wall of the hatch 12. The pushing parts 422 are columnar protrusions, and the protrusion heights are the same.

[0050] When the first rotating member 42 needs to be rotated, an external force can act on the outer surface of any one of the pushing parts 422 to apply a circumferential torque. The circumferential distribution of the pushing parts 422 enables the operator to drive the first rotating member 42 to rotate from multiple directions without adjusting the hand position. During the rotation process, a preset distance is maintained between the pushing parts 422 and the outer wall of the hatch 12 to avoid interference. When the first rotating member 42 rotates, it pulls the baffle 3 to slide through the traction rope 43. After the first lock hole 21 is exposed, the first door lock 2 can be operated. The circumferential distribution structure of the pushing parts 422 provides multiple force application points for the first rotating member 42, improving the flexibility and convenience of the rotation operation.
