DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 8 The present invention provides a silicone rubber fire-resistant bus duct, including a trough body 1 and a support seat 5 connected to the bottom of the trough body 1. The trough body 1 is connected to a busbar 2, and the trough body 1 is filled with silicone rubber. After the filling is completed, it is cured at a temperature of 150 degrees in a furnace, so that the bus duct has good fire resistance and flame retardancy, and can be used in severe and harsh environments. The support seat 5 is connected to a limiting mechanism and a clamping mechanism. The limiting mechanism includes a relatively arranged block 11, a relatively arranged connecting column 13, and a relatively arranged spring 22. The connecting column 13 is used to guide the block 11, that is, the block 11 reciprocates stably, and the spring 22 makes it move smoothly. The spring 22 is used to drive the block 11 to approach the center line direction of the support seat 5. The clamping mechanism includes a spring 18, a positioning rod 19, a relatively arranged wedge block 21, and a relatively arranged limit head 16. The spring 18 is used to drive the positioning rod 19 to move toward the direction close to the stop block 11, the positioning rod 19 is used to drive the wedge block 21 to rise and fall synchronously, and the wedge block 21 is used to drive the limit head 16 to move.

[0031] When the trough body 1 is in the positioning state, that is, the bus duct is installed, the trough body 1 is placed on the hanging plate 7 (which is an existing device and will not be described in detail here), and the support seat 5 is supported by the hanging plate 7. Due to the gravity of the trough body 1 itself, the trough body 1 moves downward, and the hanging plate 7 drives the two relative stoppers 11 to separate. At this time, the spring 22 is gradually compressed, and the hanging plate 7 moves into the connecting groove 9. The hanging plate 7 is lifted up on the positioning rod 19, and the spring 18 is compressed. The positioning rod 19 drives the lifting rod 14 and the wedge block 21 to move up synchronously. The wedge block 21 applies a thrust to the limit head 16, and the limit head 16 moves toward the center line direction close to the support seat 5. The center line is Figure 8The middle e line, at this time, the two sides of the hanging plate 7 are still connected to the tip of the stopper 11, and the limit head 16 is not in contact with the hanging plate 7. The hanging plate 7 continues to move up until the stopper 11 is connected to the limit groove 10 set on the hanging plate 7, and the hanging plate 7 stops moving. At this time, the positioning rod 19 is pressed against the top of the hanging plate 7, and the limit head 16 is pressed against the two sides of the hanging plate 7, thereby improving the stability of the connection between the support seat 5 and the hanging plate 7, that is, improving the stability of the fire-resistant bus duct, replacing the traditional bolt or welding method of fixing, and the operation is flexible and convenient.

[0032] The limiting mechanism also includes a push-pull plate 6 and a handle 8. The push-pull plate 6 is fixedly connected to the connecting column 13. The handle 8 is fixed to the push-pull plate 6. When the handle 8 is pulled, the push-pull plate 6 can drive the two side-by-side connecting columns 13 to move away from the e-line synchronously. There is no need to apply pulling force to the corresponding connecting columns 13 individually, which can shorten the disassembly time of the trough body 1.

[0033] The second spring 22 is sleeved on the connecting column 13 , and both ends of the second spring 22 are connected to the stopper 11 and the supporting seat 5 .

[0034] The stopper 11 is provided with a driving surface 12, and the driving surface 12 is a smooth surface, which reduces the contact friction and makes the tank body 1 move downward better. The stopper 11 is slidably connected with the support seat 5, so that the stopper 11 can reciprocate stably. When the tank body 1 is installed, the hanging plate 7 contacts the driving surface 12. Due to the gravity of the tank body 1 itself or a slight thrust is applied to the tank body 1, the tank body 1 can be moved downward, that is, the top of the hanging plate 7 slides on the driving surface 12, and the two stoppers 11 can be spread apart, that is, the two stoppers 11 are away from each other.

[0035] The clamping mechanism also includes a spring seat 17, a lifting plate 15 and a lifting rod 14 which are arranged opposite to each other. One end of the lifting plate 15 is fixed to the positioning rod 19. The top of the lifting rod 14 is connected to the lifting plate 15, and the bottom of one side of the lifting rod 14 is fixedly connected to the wedge block 21. The spring seat 17 is fixed in the support seat 5. Both ends of the spring 18 are connected to the spring seat 17 and the positioning rod 19. The positioning rod 19 is slidably connected to the support seat 5. Before the bus duct is installed, the bottom of the positioning rod 19 protrudes from the inner top of the connecting groove 9, the limit head 16 is located in the support seat 5, and one end of the limit head 16 is at a distance from the inner side of the connecting groove 9. After the bus duct is installed, the top of the hanging plate 7 is connected to the inner top of the connecting groove 9, and the two sides of the hanging plate 7 are connected to the inner side of the connecting groove 9. The positioning rod 19 and the limit head 16 are both pressed against the hanging plate 7.

[0036] The other end of the lifting plate 15 is slidably connected to the inner side of the support seat 5, so that the positioning rod 19, the lifting rod 14, and the wedge block 21 can be lifted and lowered stably without being skewed or offset.

[0037] The limit head 16 is slidably connected to a sliding surface 20 provided on the wedge block 21. The sliding surface 20 is an inclined surface. The limit head 16 and the wedge block 21 are inseparable. When the wedge block 21 rises, the end of the limit head 16 slides on the sliding surface 20, and the limit head 16 moves toward the direction close to the e line; when the wedge block 21 descends, the end of the limit head 16 slides on the sliding surface 20, and the limit head 16 moves away from the e line.

[0038] Both ends of the trough body 1 are sealed with a sealing baffle 3 and a guard plate 4. The busbar 2 passes through the sealing baffle 3, and the sealing baffle 3 is sealed and connected to the busbar 2 to prevent silicone rubber from leaking from the connection between the busbar 2 and the sealing baffle 3. The guard plate 4 is located on both sides of the busbar 2.

[0039] The installation method of silicone rubber fire-resistant bus duct includes the following steps:

[0040] Step 1: Place the tank body 1 on the top of the hanging plate 7, and drive the hanging plate 7 to separate the two relative stoppers 11 and move into the connecting groove 9;

[0041] Step 2: The hanging plate 7 is lifted up on the positioning rod 19, the spring 18 is compressed, the positioning rod 19 drives the lifting rod 14 and the wedge block 21 to move upward synchronously, the wedge block 21 applies a thrust to the limit head 16, and the limit head 16 moves toward the center line direction of the support seat 5. At this time, the two sides of the hanging plate 7 are still connected to the tip of the stop block 11, and the limit head 16 is not in contact with the hanging plate 7;

[0042] Step 3: The hanging plate 7 continues to move upward relative to the support seat 5, the stopper 11 is connected to the limiting groove 10 provided on the hanging plate 7, the positioning rod 19 is pressed against the top of the hanging plate 7, and the limiting head 16 is pressed against both sides of the hanging plate 7;

[0043] Step 4: Pull the handle 8, the stopper 11 moves away from the center line of the support seat 5, the top of the support seat 5 is disengaged from the limiting groove 10, and the groove body 1 is pulled to separate from the hanging plate 7.

[0044] Working principle: Place the trough body 1 above the hanging plate 7, so that the support seat 5 is connected to the hanging plate 7. Due to the gravity of the trough body 1, the trough body 1 moves downward, that is, the hanging plate 7 moves upward relative to the trough body 1, and the top of the hanging plate 7 is connected to the driving surface 12 of the stopper 11, which can open the two stoppers 11, and the spring 22 is compressed. The hanging plate 7 continues to move upward, and the top of the hanging plate 7 can lift the positioning rod 19, the spring 18 is compressed, and the positioning rod 19 drives the lifting plate 15 to move upward, that is, the lifting rod 14 and the wedge block 21 move upward synchronously, and the wedge block 21 drives the limit head 16 to move close to the e line, at which time the limit head 16 is not connected to the hanging plate 7. The hanging plate 7 moves up again, and continues to lift the positioning rod 19 until the top of the hanging plate 7 is connected to the top of the connecting groove 9 and stops moving. At this time, the compressed spring 22 releases the elastic force, that is, the stopper 11 is connected to the limiting groove 10 set on the hanging plate 7 to achieve preliminary limiting. At the same time, the spring 18 is further compressed, that is, the positioning rod 19 is pressed against the top of the hanging plate 7, and the limiting head 16 is pressed against the two sides of the hanging plate 7 to achieve full locking, improve the stability of the connection between the support seat 5 and the hanging plate 7, and then improve the stability of the bus duct, and save time and effort in installation. When the bus duct needs to be disassembled, just pull the handle 8 to drive the stopper 11 away from the e-line. When the stopper 11 is disengaged from the limiting groove 10, the support seat 5 is in a relaxed state, and the trough body 1 is lifted to facilitate separation from the hanging plate 7, that is, the disassembly is more flexible and convenient, and the practicability is strong.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
