Description

Technical Field

[0001] The invention relates to a quick disassembly and assembly fixture suitable for the lower installation of a photovoltaic component at a high place. Background Art

[0002] Today, as the global utilization of new energy and environmental awareness increase, the combination of photovoltaic power generation technology and green buildings has become a mainstream concept, and the combination of photovoltaic power generation systems and carports installed at high places is particularly prominent. Without changing the original function of the carport, a photovoltaic power generation system is installed on the top of the carport to give new functions and value to the original building. The height of the carport is 3m-5m. To install photovoltaic modules on the top of a conventional photovoltaic carport, you need to climb to the top of the carport, which is dangerous. At the same time, workers standing on the photovoltaic modules will step on the photovoltaic modules, causing risks such as module rupture and hidden cracks. Conventional installation requires the use of block screws for installation, which has problems such as low operating efficiency and cumbersome operation when replacing damaged photovoltaic modules. Summary of the invention

[0003] The purpose of the present invention is to provide a quick disassembly and assembly fixture suitable for the lower installation of high-altitude photovoltaic components. The lower installation can be performed without climbing to the top of the carport or stepping on the photovoltaic components. The use is quick and convenient.

[0004] The object of the present invention is achieved in this way. A quick disassembly and assembly fixture suitable for the lower installation method of a high-rise photovoltaic component is divided into two major parts: an upper structure and a lower structure; wherein the upper structure comprises: a photovoltaic component, an eccentric pressure block, a pin shaft, a cavity holder, a lock spring tongue, a spring tongue spring, a linkage pin shaft, and a pin shaft spring. A protruding support pin hole is provided at the top of the cavity holder, a pin shaft is provided in the pin hole, an eccentric pressure block is installed on the pin shaft, the eccentric pressure block consists of an eccentric pressure head and a handle, the eccentric pressure block rotates around the pin shaft, and the eccentric pressure head consists of an eccentric circle; a rectangular slide groove is provided in the horizontal direction inside the cavity holder, a lock spring tongue is provided in the slide groove, and two spring tongue springs are provided at the rear end of the lock spring tongue, and the lock spring tongue extends or retracts in the horizontal direction; a circular pin hole is provided in the vertical direction of the cavity holder, a linkage pin shaft is provided in the pin hole, and a pin shaft spring is provided outside the linkage pin shaft, and the linkage pin shaft moves in the vertical direction; the cavity holder is provided with a circular pin hole in the vertical direction, a linkage pin shaft is provided in the pin hole, and a pin shaft spring is provided outside the linkage pin shaft, and the linkage pin shaft moves in the vertical direction; the cavity holder The cross section is a hollow design, which enhances the structural strength and reduces the deadweight of the structure. The lower structure includes a movable lock, a fixed lock, a fixed support, a fixed pin, a support spring, a cross arm, and an M-shaped water tank. The fixed support presents a cross-shaped structure with fixed locks connected on both sides. Two rectangular slides with one end open are arranged on the upper part of the fixed support. The two rectangular slides are symmetrically distributed on both sides of the upper part of the fixed support. The slide on the upper part of the fixed support is connected to the rectangular slider at the rear end of the movable lock by surface contact. A fixing pin is arranged on the top of the fixed support to limit the movable lock and prevent the movable lock from escaping from the top of the fixed support. The lower part of the movable lock is connected to the fixed lock by a support spring. The function of the support spring is to support the movable lock, thereby supporting the entire upper structure. A slide is arranged inside the cavity seat in the upper structure, which is connected to the movable lock and the fixed lock in the lower structure by surface contact, so that only linear movement in the vertical direction can be made between the upper structure and the lower structure.

[0005] When the upper structure of the present invention is working: the cavity holder is the main structure of the upper structure, and is responsible for the functions of transferring the load of the upper structure, connecting components, and cooperating with the lower structure. The cavity holder is connected to the eccentric pressure block through a pin. When the eccentric pressure block is in a free state, the handle is lifted up to keep it loose. When the photovoltaic module needs to be installed, the lower frame of the photovoltaic module is placed on the top surface of the cavity holder, and then the handle of the eccentric pressure block is turned downward. The handle drives the eccentric pressure head to press the lower frame of the photovoltaic module. The locking tongue can move horizontally inside the cavity holder, and when extended, it locks the entire mechanism to prevent disengagement. When retracted, the entire mechanism is unlocked. The upper structure is unlocked and disengaged from the lower structure.

[0006] When the lower structure is working: the fixed support is the main structure of the lower structure, responsible for transmitting the load of the upper structure, connecting the fixed lock buckle and the movable lock buckle through the slider slot, and connecting with the cross arm through the support bolt hole set at the bottom, so as to effectively connect the entire structure of the present invention with the main structure. The movable lock buckle cooperates with the rectangular slots on both sides of the top of the fixed support through the rear rectangular slider, so that the movable lock buckle can move linearly in the vertical direction relative to the fixed support.

[0007] The present invention has a linkage locking function. When the eccentric pressure block is in a downward locking state, the linkage pin is pushed downward to move, and the lower end of the linkage pin is inserted into the rear end of the lock spring tongue, which presses against the lock spring tongue so that it cannot retract, thereby locking the entire mechanism. When unlocking, when the eccentric pressure block is in an upward relaxed state, the pin spring pushes the linkage pin upward, and the lock spring tongue is in an unlocked state and can retract.

DETAILED DESCRIPTION

[0010] A quick disassembly and assembly fixture suitable for the lower installation of high-rise photovoltaic modules, such as Figure 1-6As shown, it is divided into two parts: an upper structure and a lower structure; the upper structure includes: a photovoltaic component 1, an eccentric pressure block 2, a pin shaft 3, a cavity holder 4, a lock spring tongue 6, a spring tongue spring 6001, a linkage pin shaft 11, and a pin shaft spring 12. A protruding support pin hole is provided on the top of the cavity holder 4, a pin shaft 3 is provided in the pin hole, an eccentric pressure block 2 is installed on the pin shaft, and the eccentric pressure block 2 is composed of an eccentric pressure head and a handle. The eccentric pressure block 2 rotates around the pin shaft 3, and the eccentric pressure head is composed of two eccentric circles. ; A rectangular slide groove in the horizontal direction is arranged inside the cavity card seat 4, a lock spring tongue 6 is arranged in the slide groove, and two spring tongue springs 6001 are arranged at the rear end of the lock spring tongue 6, and the lock spring tongue 6 is extended or retracted in the horizontal direction; a circular pin hole is arranged in the vertical direction of the cavity card seat 4, a linkage pin shaft 11 is arranged in the pin hole, and a pin shaft spring 12 is arranged on the outer sleeve of the linkage pin shaft 11, and the linkage pin shaft 11 moves in the vertical direction; the cross section of the cavity card seat 4 is a hollow design to enhance the structural strength At the same time, it reduces the deadweight of the structure; the lower structure includes a movable lock buckle 5, a fixed lock buckle 7, a fixed support 8, a fixed pin 9, a support spring 10, a cross arm 13, and an M-shaped water tank 14. The fixed support 8 presents a cross-shaped structure, and the fixed lock buckle 7 is connected to the two sides. Two rectangular slide grooves with one end open are arranged on the upper part of the fixed support 8, and the two rectangular slide grooves are symmetrically distributed on both sides of the upper part of the fixed support 8. The slide groove on the upper part of the fixed support 8 is connected with the rectangular slider at the rear end of the movable lock buckle 5 by surface contact. A fixing pin 9 is arranged on the top of the fixed support 8 to limit the movable lock buckle 5 and prevent the movable lock buckle 5 from escaping from the top of the fixed support 8. The lower part of the movable lock buckle 5 is connected with the fixed lock buckle 7 by a support spring 10. The function of the support spring 10 is to support the movable lock buckle 5, thereby supporting the entire upper structure; a slide groove is arranged inside the cavity seat 4 in the upper structure, which is connected with the movable lock buckle 5 and the fixed lock buckle 7 in the lower structure by surface contact, so that only linear movement in the vertical direction can be made between the upper structure and the lower structure.

[0011] like Figure 1 , 2 As shown, the actual application process of the present invention can be divided into two states: quick installation and locking and quick unlocking and disassembly. The connection between the upper structure and the lower structure of the present invention is through the rectangular slide groove provided in the cavity seat 4 and the slider provided in the movable lock 5 and the fixed lock 7 in a surface contact manner. The cooperation method is as follows Figure 3 , Figure 4 shown.

[0012] The quick installation and locking process is as follows: the upper structure is installed on the lower frame of the photovoltaic module 1, and the eccentric pressing block 2 is temporarily kept in a lifted and relaxed state.

[0013] The upper structure with the photovoltaic module 1 installed is vertically inserted into the lower structure. When the lock spring tongue 6 arranged in the cavity holder 4 contacts the inclined surface of the front end (outside) of the movable lock 5, the lock spring tongue 6 will compress the spring tongue spring 6001, so that the lock spring tongue 6 is retracted to the inside (outside) of the cavity holder 4. The upper structure continues to move downward until the lock spring tongue 6 is between the fixed lock 7 and the fixed support 8. The spring tongue spring 6001 pushes the lock spring tongue 6 outward under the action of elastic force.

[0014] The handle of the eccentric pressing block 2 in the upper structure is pressed downward, and the eccentric pressing block 2 presses the lower frame of the photovoltaic module 1. At the same time, the handle pushes the linkage pin 11 downward, and the lower end of the linkage pin 11 is inserted into the rear end of the above-mentioned lock spring tongue 6 to prevent it from retracting, thus completing the locking. The locking state is as follows: Figure 2 Shown on the left.

[0015] At this time, the upper structure cannot be pulled upward due to the blocking of the lock spring tongue 6, and at the same time, due to the elastic force of the support spring 10, the upper structure cannot sink downward, and can only move in a small range in the vertical direction to protect the photovoltaic components from being damaged. The linkage pin 11 blocks the lock spring tongue 6 from retracting. This can prevent the entire structure from being accidentally unlocked and falling off during non-human operation.

[0016] The quick unlocking and disassembly process is as follows: when the photovoltaic module needs to be removed, you only need to stand under the photovoltaic module and pull the handle of the eccentric pressure block 2 upwards. The pin spring 12 will push the linkage pin 11 upwards, and the lock spring tongue 6 will be in an unlocked state and can retract. Continue to press the lower frame of the photovoltaic module 1 downwards. At this time, the upper structure will move downward as a whole with the photovoltaic module 1. When the lock spring tongue 6 contacts the inclined surface of the front end (outside) of the fixed lock 7, the lock spring tongue 6 will compress the spring tongue spring 6001, so that the lock spring tongue 6 is retracted to the inside (outside) of the cavity seat 4, and the upper structure continues to move downward until the bottom surface of the movable lock 5 and the top surface of the fixed lock 7 are tightly fitted. At this time, the inclined surfaces of the movable lock 5 and the fixed lock 7 are tightly fitted synchronously, and the side surfaces of the movable lock 5 and the fixed lock 7 form a vertical plane at this time, so that the lock spring tongue 6 cannot be ejected, and the locking fails. Then lift the upper structure upwards to separate the upper structure of the present invention from the lower structure, thereby realizing the function of quick removal of the photovoltaic module. Figure 2 Shown on the right.

[0017] The present invention is a lower installation method that does not require cumbersome bolt and nut pressing operations and can be operated without climbing onto the upper part of the photovoltaic module. One-stage pressing fixes the lock, and two-stage pressing unlocks and disengages. The present invention has linkage locking and unlocking functions. The linkage pin 11 blocks the lock spring tongue 6 from retracting. The operation is simplified while providing mechanism reliability. The entire structure can be prevented from accidentally unlocking and falling off during non-human operation.

[0018] Conventional photovoltaic module clamps use the same set of clamp devices for the left and right photovoltaic modules. When a photovoltaic module needs to be replaced, the removal of the clamp will cause the fixation of other photovoltaic modules to fail, resulting in damage to the photovoltaic modules and personnel safety risks. The present invention effectively solves the above problems. The clamp scheme proposed by the present invention exists independently on the left and right. Each photovoltaic module has an independent quick-fastening and disassembly clamp. When a single or partial photovoltaic module needs to be disassembled, the effective fastening of other photovoltaic modules is not affected. The safety of photovoltaic modules and operators is greatly protected. The lower part of the movable lock 5 is connected to the fixed lock 7 through a support spring 10. The function of the support spring 10 is to support the movable lock 5, thereby supporting the entire upper structure. This setting allows the entire photovoltaic module to have a flexible connection, and partial elastic deformation can be achieved in the vertical direction. When encountering heavy objects hitting, strong winds and heavy snow, the support spring 10 can absorb energy to prevent the photovoltaic module from being damaged. At the same time, according to the existing patents, there is a scheme for vibrating or knocking the frame of the photovoltaic module to achieve vibration snow and ice removal, but the existing vibration knocking deicing patents do not take into account the damage to the rigid connection of the photovoltaic module and the risk of photovoltaic module breakage caused by vibration knocking. The present invention makes up for the above-mentioned shortcomings of snow and ice removal by vibration knocking.

[0019] The fixed support 8 presents a cross-shaped structure, with fixed lock buckles 7 connected on both sides. Two rectangular slide grooves with one end open are arranged on the top of the fixed support 8, and the two rectangular slide grooves are symmetrically distributed on both sides of the top of the fixed support 8. The slide groove on the top of the fixed support 8 is connected with the rectangular slider at the rear end of the movable lock buckle 5 by surface contact. A fixing pin 9 is arranged on the top of the fixed support 8 to limit the movable lock buckle 5 and prevent the movable lock buckle 5 from escaping from the top of the fixed support 8. The present invention has the functions of eccentric clamping quick disassembly and assembly and two-stage pressing quick disassembly and assembly. The two quick installation and disassembly devices work together to greatly improve the installation and disassembly efficiency.
