Description

Technical Field

[0001] The invention belongs to the technical field of nuclear power engineering building construction, and in particular relates to an edge protection device for the construction of exterior wall panels of nuclear power engineering buildings. Background Art

[0002] Nuclear power projects are large-scale engineering projects that use the fission reaction of nuclear fuel in nuclear reactors to generate heat energy, which is then converted into electrical energy. It usually includes a nuclear island, a conventional island and related supporting facilities. The nuclear island is the core part, which contains key equipment such as the reactor pressure vessel and is responsible for the generation and control of nuclear energy. The conventional island converts heat energy into electrical energy. Nuclear power projects have the advantages of being clean, efficient and stable. They can provide electricity on a large scale, reduce dependence on fossil energy and reduce carbon emissions. However, they also face nuclear safety risks. Therefore, there are strict safety standards and regulatory measures in the design, construction, operation and other links to ensure that public safety and the environment are not affected. In the construction of building exterior wall panels, the main function of the edge protection device is to prevent construction workers and objects from falling from the edge of the building, provide safety protection for construction workers, reduce the risk of height-falling accidents, and avoid damage to surrounding personnel and facilities caused by falling objects, ensuring the safety and order of the construction site.

[0003] In the construction of exterior wall panels, most existing methods use cantilevered protective structures. During installation, the exterior wall panels may fall off due to loose fixation or external force. The cantilevered protective shed can intercept them below the working surface to prevent them from falling directly to the ground. At the same time, it can prevent the falling point from being too high, causing the objects to pass through the protection area. However, most existing edge guardrails are simple guardrail structures with relatively single functions. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an edge protection device for the construction of exterior wall panels of nuclear power engineering buildings.

[0005] The technical solution adopted to solve the above technical problems is: to provide an edge protection device for the construction of exterior wall panels of nuclear power engineering buildings, comprising a guardrail main body mechanism, the center of which is fixedly connected to a central mesh plate mechanism, and both sides of the bottom of the front end of the guardrail main body mechanism are rotatably connected to bottom bracket mechanisms;

[0006] The bottom of the rear end of the guardrail main body mechanism is rotatably connected to an auxiliary protection structure, and a storage drive mechanism is provided on the top of the guardrail main body mechanism. One end of the storage drive mechanism is fixedly connected to a limiting mechanism, and connecting steel wires are installed between the storage drive mechanism and both sides of the auxiliary protection structure and one end of the two bottom bracket mechanisms.

[0007] Furthermore, the guardrail main body mechanism includes a guardrail support frame, a hollow pillar is fixedly connected between the two ends of the top of the guardrail support frame, a first connection hole plate and a second connection hole plate are fixedly connected to the bottom of both sides of the guardrail support frame, and a blocking frame rod is fixedly connected between the first and second connection hole plates and the side of the guardrail support frame. Connecting shaft seats are provided on both sides of the bottom of the guardrail support frame. When in use, two such protective devices are spliced ​​together, and the first and second connection hole plates at different heights on both sides of the guardrail support frame are overlapped with each other, and are fixed by bolts through corresponding through-holes. The entire device is fixed to the edge of the cantilever platform and spliced ​​and fixed. The two connecting shaft seats can realize the rotational connection of the two bottom bracket mechanisms.

[0008] Furthermore, the first connection hole plate and the second connection hole plate are not on the same horizontal plane.

[0009] The above technical solution ensures that when two protective devices are spliced ​​together, the first connecting hole plate and the second connecting hole plate can overlap each other and then be connected and fixed by bolts.

[0010] Furthermore, the central mesh plate mechanism includes a bottom baffle fixedly connected to the guardrail support frame, the top of the bottom baffle is fixedly connected to an integrated frame, and the inner wall of the integrated frame is fixedly connected to a wire protection net.

[0011] Through the above technical solution, the bottom baffle can prevent some small objects from being kicked out, and the wire mesh can effectively prevent some objects from passing through the overall central mesh plate mechanism.

[0012] Furthermore, the bottom bracket mechanism includes a connecting shaft sleeve seat rotatably connected to the bottom of the front end of the guardrail main body mechanism, the front end surface of the connecting shaft sleeve seat is fixedly connected to a support connecting piece, and equalizing plates are provided on both sides of the front end of the support connecting piece. Two fixing bolts are passed through the two equalizing plates and the support connecting piece, and the front end of the top of the support connecting piece is rotatably connected to a first steel wire connecting piece.

[0013] Through the above technical solution, the connecting steel wire is released by the storage drive mechanism to realize the rotation and lowering of the overall bottom bracket mechanism. At this time, the two bottom bracket mechanisms are placed horizontally and fit the platform, and the overall support connector is installed on the nut seat of the platform through the fixing bolts.

[0014] Furthermore, the auxiliary protection structure includes a rotating frame rotatably connected to the bottom rear end of the guardrail main body mechanism, the bottoms on both sides of the rotating frame are fixedly connected with fixed shaft blocks, the front ends on both sides of the top of the rotating frame are installed with slide groove blocking covers, the inner wall of the rotating frame is installed with a first protective rope net, fixed clamping shafts are provided on both sides of the top of the rotating frame, permanent magnet blocks are fixedly connected at the rear ends of the fixed clamping shafts on both sides of the rotating frame, T-shaped limit rods are fixedly connected on both sides of the inner wall of the rotating frame, a sliding frame is fixedly connected between the tops of the two T-shaped limit rods, iron connecting clamps are rotatably connected on both sides of the bottom of the sliding frame, a second protective rope net is installed on the inner wall of the sliding frame, and second steel wire connectors are rotatably connected on both sides of the top of the sliding frame.

[0015] By the above technical solution, the connecting wire is released by the storage driving mechanism, and the auxiliary protective structure after the connecting wire is released reaches the maximum angle. At this time, the connecting wire is pulled to rotate and pull up the auxiliary protective structure, and then the top of the sliding frame is pulled until it slides to the maximum stroke. At this time, the two T-shaped limit rods slide on both sides of the inner wall of the rotating frame until they hit the slide groove blocking cover. At this time, the two iron connecting clamps are rotated and then engaged with the corresponding fixed clamping shafts. At the same time, the iron connecting clamps are adsorbed by two corresponding permanent magnets to prevent the entire sliding frame from sliding downward, and then the connecting wire is released. The opened auxiliary protective structure rotates to the maximum angle within the limit of the length of the connecting wire. The expanded auxiliary protective structure can effectively increase the range of the edge protection device and reduce the safety hazard of objects falling from high altitude. When the auxiliary protective structure is hit by an object, the impact force can be transmitted to the guardrail main body mechanism through the connecting wire and its own structure, and then transmitted to the two bottom bracket mechanisms through the connecting wire, thereby ensuring the stability of the overall device when facing impact.

[0016] Furthermore, sliding grooves corresponding to the T-shaped limiting rods are provided on both sides of the inner wall of the rotating frame.

[0017] With the above technical solution, the extended sliding frame is supported by the sliding groove and the two T-shaped limiting rods, so that the rotating frame and the sliding frame become a whole.

[0018] Furthermore, the storage drive mechanism includes two side blocking shaft plates installed on both sides of the top of the guardrail main body mechanism, and a connecting shaft rod is rotatably connected between the two side blocking shaft plates, and the first winding wheel and the second winding wheel are fixedly connected on both sides of the outer wall of the connecting shaft rod.

[0019] Through the above technical solution, the limiting mechanism is used to drive the rotation of the connecting shaft, thereby driving the two first winding wheels and the two second winding wheels to rotate simultaneously, thereby releasing and winding the connecting steel wire, and then realizing the opening and closing of the auxiliary protective structure and the two bottom bracket mechanisms.

[0020] Furthermore, both the first winding wheel and the second winding wheel have connecting steel wires wound on them, the length of the connecting steel wire on the first winding wheel is smaller than the length of the connecting steel wire on the second winding wheel, and the diameter of the first winding wheel is smaller than the diameter of the second winding wheel.

[0021] Through the above technical solution, since the fully extended auxiliary protection structure is longer, the distance between the first steel wire connector and the storage drive mechanism is smaller than the distance between the second steel wire connector and the storage drive mechanism, so the connecting steel wires between the two are different. At the same time, in order to ensure that the first winding wheel and the second winding wheel rotate the same number of times, the two connecting steel wires of different lengths can be fully released at the same time. Therefore, the longer connecting steel wire is designed to be wound on the second winding wheel with a larger diameter, and the shorter connecting steel wire is wound on the first winding wheel with a smaller diameter.

[0022] Furthermore, the limiting mechanism includes a fixed circular sleeve fixedly connected to one side of the side blocking shaft plate and an integrated square groove seat fixedly connected to one end of the connecting shaft rod, one side of the inner wall of the fixed circular sleeve is rotatably connected to a rotating circular block, the rotating circular block is fixedly connected to a square pin at the center of one side close to the integrated square groove seat, the outer wall of the rotating circular block is fixedly connected to an extension rod, the outer wall of the extension rod is rotatably connected to an adjusting block, a reset spring is arranged between the integrated square groove seat and the rotating circular block, the other side of the outer wall of the fixed circular sleeve is fixedly connected to a rotating limit block, and the fixed circular sleeve is provided with a slot corresponding to the rotating limit block.

[0023] According to the above technical solution, after the initial fixation is completed, the adjusting block is rotated and the integral rotating block is pulled outward, and the reset spring is stretched. At the same time, the rotation limit block is pulled out of the groove. The position of the rotating block after being pulled out is limited by placing the adjusting block horizontally, so as to prevent the rotating block from being reset under the action of the reset spring. Then, the rotating block is driven to rotate by the extension rod, and then the square latch is engaged inside the integrated square groove seat to drive the integrated square groove seat and the connecting shaft rod fixed thereto to rotate, thereby releasing the auxiliary protective structure and the bottom bracket mechanism. When the overall protective device is subsequently disassembled, the rotating block is driven to rotate in the opposite direction, thereby driving the two first winding wheels and the two second winding wheels to reel in the multiple connecting wires. After the wires are fully reeled, the rotating adjusting block is in a vertical state. Under the action of the reset spring, the rotating block retracts at this time, and the rotation limit block is engaged in the slot to limit the rotation of the rotating block, thereby limiting the position of the connecting shaft rod, thereby preventing the bottom bracket mechanism and the auxiliary protective structure from being deflected due to the rotation of the connecting shaft rod.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention can effectively increase the range of the edge protection device by designing a retractable and extendable auxiliary protection structure, reducing the safety hazard of objects falling from high altitudes. When the auxiliary protection structure is hit by an object, the impact force can be transmitted to the guardrail main body through the connecting steel wire and its own structure, and then transmitted to the two bottom bracket mechanisms through the connecting steel wire, thereby ensuring the stability of the entire device when facing an impact. At the same time, the retractable auxiliary protection structure can be stored by the guardrail main body after retraction, while improving the functionality of the overall protection device without increasing the space occupied by the overall protection device; (2) The present invention drives the bottom bracket mechanism and the auxiliary protection structure at the same time by designing a storage drive mechanism and a connecting steel wire. The bottom bracket mechanism and the auxiliary protection structure can be released and stored at the same time, which greatly improves the installation efficiency and disassembly and recovery efficiency of the device, ensures diverse functions without increasing additional installation and recovery time, and improves work efficiency.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0048] like Figure 1-Figure 3As shown, an edge protection device for the construction of exterior wall panels of a nuclear power engineering building in this embodiment includes a guardrail main body mechanism 1, which includes a guardrail support frame 101. A hollow pillar 102 is fixedly connected between the two ends of the top of the guardrail support frame 101. The bottoms of both sides of the guardrail support frame 101 are respectively fixedly connected with a first connecting hole plate 103 and a second connecting hole plate 104. The first connecting hole plate 103 and the second connecting hole plate 104 are fixedly connected to the side surfaces of the guardrail support frame 101. A blocking frame rod 105 is fixedly connected between the first connecting hole plate 103 and the second connecting hole plate 104 and the side surfaces of the guardrail support frame 101. A connecting shaft seat 106 is provided on both sides of the bottom of the guardrail support frame 101. When in use, The two protective devices are spliced ​​together, and the first connecting hole plates 103 and the second connecting hole plates 104 at different heights on both sides of the guardrail support frame 101 are overlapped with each other, and fixed with bolts through the corresponding through holes, and the entire device is fixed to the edge of the cantilever platform and spliced ​​and fixed. The two bottom bracket mechanisms 3 can be rotatably connected through the two connecting shaft seats 106. The first connecting hole plates 103 and the second connecting hole plates 104 are not on the same horizontal plane, ensuring that when the two protective devices are spliced ​​together, the first connecting hole plates 103 and the second connecting hole plates 104 can overlap with each other and be connected and fixed by bolts.

[0049] like Figure 1-Figure 5 As shown, the center of the guardrail main body mechanism 1 is fixedly connected to the central mesh plate mechanism 2, and the central mesh plate mechanism 2 includes a bottom baffle 201 fixedly connected to the guardrail support frame 101, and the top of the bottom baffle 201 is fixedly connected to the integrated frame 202, and the inner wall of the integrated frame 202 is fixedly connected to the wire protection net 203. The bottom baffle 201 can prevent some small objects from being kicked out, and the wire protection net 203 can effectively prevent some objects from passing through the entire central mesh plate mechanism 2. The bottom sides of the front end of the guardrail main body mechanism 1 are rotatably connected to the bottom bracket mechanism 3, and the bottom bracket mechanism 3 includes a bottom bracket mechanism 3 rotatably connected to the guardrail main body mechanism 1. The connecting shaft sleeve seat 301 at the bottom of the front end, the front end surface of the connecting shaft sleeve seat 301 is fixedly connected to the support connecting piece 302, and equalizing plates 303 are provided on both sides of the front end of the support connecting piece 302. Two fixing bolts 304 are passed through the two equalizing plates 303 and the support connecting piece 302. The front end of the top of the support connecting piece 302 is rotatably connected to the first steel wire connecting piece 305. The connecting steel wire 7 is released by the storage drive mechanism 5 to realize the rotation and downward transfer of the overall bottom bracket mechanism 3. At this time, the two bottom bracket mechanisms 3 are horizontally placed to fit the platform, and the overall support connecting piece 302 is installed on the nut seat of the platform by fixing bolts 304.

[0050] like Figures 1-10As shown, the bottom of the rear end of the guardrail main body mechanism 1 is rotatably connected to the auxiliary protection structure 4, and the auxiliary protection structure 4 includes a rotating frame 401 rotatably connected to the bottom of the rear end of the guardrail main body mechanism 1, and the bottoms on both sides of the rotating frame 401 are fixedly connected to fixed shaft blocks 402, and the front ends of both sides of the top of the rotating frame 401 are installed with slide groove blocking covers 403, and the inner wall of the rotating frame 401 is installed with a first protective rope net 404, and fixed card shafts 405 are provided on both sides of the top of the rotating frame 401. Permanent magnet blocks 406 are fixedly connected to the rear ends of the fixed card shafts 405 on both sides of the rotating frame 401. The inner wall of the frame 401 is fixedly connected with a T-shaped limit rod 410 on both sides, and a sliding frame 407 is fixedly connected between the tops of the two T-shaped limit rods 410. The bottom of the sliding frame 407 is rotatably connected with an iron connecting card 408 on both sides. The inner wall of the sliding frame 407 is installed with a second protective rope net 409. The top of the sliding frame 407 is rotatably connected with a second steel wire connector 411 on both sides. The connecting wire 7 is released by the storage drive mechanism 5. The auxiliary protective structure 4 after the connecting wire 7 is released reaches the maximum angle. At this time, the connecting wire 7 is pulled to rotate and pull up the auxiliary protective structure 4, and then the connecting wire 7 is pulled up. The top of the movable sliding frame 407 is rotated until it slides to the maximum stroke. At this time, the two T-shaped limit rods 410 slide on both sides of the inner wall of the rotating frame 401 until they hit the slide groove blocking cover 403. At this time, the two iron connecting clamps 408 are rotated and then engaged with the corresponding fixed clamping shafts 405. At the same time, the two corresponding permanent magnets 406 are used to adsorb the iron connecting clamps 408 to prevent the entire sliding frame 407 from sliding downward. Then the connecting wire 7 is released, and the opened auxiliary protection structure 4 is rotated to the maximum angle under the limit of the length of the connecting wire 7. The expanded auxiliary protection structure 4 can effectively increase the edge defense The scope of the protective device is expanded, reducing the safety hazard of objects falling from high places. When the auxiliary protective structure 4 is hit by an object, the impact force can be transmitted to the guardrail main body mechanism 1 through the connecting steel wire 7 and its own structure, and then transmitted to the two bottom bracket mechanisms 3 through the connecting steel wire 7, thereby ensuring the stability of the entire device when facing impact. Sliding grooves corresponding to the T-shaped limit rods 410 are provided on both sides of the inner wall of the rotating frame 401. The sliding grooves and the two T-shaped limit rods 410 are used to provide support for the extended sliding frame 407, so that the rotating frame 401 and the sliding frame 407 become a whole.

[0051] like Figures 1-15As shown, a storage drive mechanism 5 is provided on the top of the guardrail main body mechanism 1, and the storage drive mechanism 5 includes two side blocking shaft plates 501 installed on both sides of the top of the guardrail main body mechanism 1, and a connecting shaft 502 is rotatably connected between the two side blocking shaft plates 501, and the first winding wheel 503 and the second winding wheel 504 are fixedly connected on both sides of the outer wall of the connecting shaft 502. The rotation of the connecting shaft 502 is driven by the limiting mechanism 6, and then the two first winding wheels 503 and the two second winding wheels 504 are driven to rotate at the same time to realize the release and winding of the connecting steel wire 7, thereby realizing the opening and closing of the auxiliary protective structure 4 and the two bottom bracket mechanisms 3. The connecting steel wire 7 is wound on the first winding wheel 503 and the second winding wheel 504. The length of the connecting steel wire 7 is smaller than the length of the connecting steel wire 7 on the second winding wheel 504, and the diameter of the first winding wheel 503 is smaller than the diameter of the second winding wheel 504. Since the fully extended auxiliary protective structure 4 is longer, the distance between the first steel wire connector 305 and the storage drive mechanism 5 is smaller than the distance between the second steel wire connector 411 and the storage drive mechanism 5. Therefore, the connecting steel wires 7 between the two are different. At the same time, in order to ensure that the first winding wheel 503 and the second winding wheel 504 rotate the same number of times, the two connecting steel wires 7 of different lengths can be released completely at the same time. Therefore, the longer connecting steel wire 7 is designed to be wound on the second winding wheel 504 with a larger diameter, and the shorter connecting steel wire 7 is wound on the first winding wheel 503 with a smaller diameter.

[0052] like Figures 1-21As shown, one end of the storage drive mechanism 5 is fixedly connected to the limiting mechanism 6, which includes a fixed circular sleeve 601 fixedly connected to one side of the side blocking shaft plate 501 and an integrated square groove seat 602 fixedly connected to one end of the connecting shaft 502. One side of the inner wall of the fixed circular sleeve 601 is rotatably connected to a rotating circular block 604. The rotating circular block 604 is fixedly connected to a square latch 605 at the center of one side close to the integrated square groove seat 602. The outer wall of the rotating circular block 604 is fixedly connected to an extension rod 607. The outer wall of the extension rod 607 is rotatably connected to the adjusting block 60 8. A return spring 603 is provided between the integrated square groove seat 602 and the rotating circular block 604. A rotation limit block 606 is fixedly connected to the other side of the outer wall of the fixed circular sleeve 601, and the fixed circular sleeve 601 is provided with a slot corresponding to the rotation limit block 606. After the initial fixation is completed, the adjusting block 608 is rotated and the entire rotating circular block 604 is pulled outward, and the return spring 603 is stretched. At the same time, the rotation limit block 606 is pulled out of the groove. The position of the rotating circular block 604 after being pulled out is limited by rotating the adjusting block 608 horizontally to avoid The round block 604 is rotated to reset under the action of the reset spring 603, and then the extension rod 607 is used to drive the rotating round block 604 to rotate, and then the square latch 605 is engaged inside the integrated square groove seat 602 to drive the integrated square groove seat 602 and the connecting shaft 502 fixedly connected thereto to rotate, thereby releasing the auxiliary protection structure 4 and the bottom bracket mechanism 3. When the overall protection device is subsequently disassembled, the rotating round block 604 is driven in the reverse direction to rotate, thereby driving the two first winding wheels 503 and the two second winding wheels 504 to rotate. The connecting steel wire 7 is wound until it is completely wound, and the rotating adjustment block 608 is in a vertical state. Under the action of the reset spring 603, the rotating circle 604 retracts, and the rotating limit block 606 is stuck in the slot to limit the rotation of the rotating circle 604, thereby limiting the rotation of the connecting shaft 502, preventing the connecting shaft 502 from rotating and causing the bottom bracket mechanism 3 and the auxiliary protection structure 4 to deflect. The storage drive mechanism 5 is respectively installed with a connecting steel wire 7 between the two sides of the auxiliary protection structure 4 and one end of the two bottom bracket mechanisms 3.

[0053] The working principle of this embodiment is as follows: when in use, two of the protective devices are spliced ​​together, and the first connecting hole plates 103 and the second connecting hole plates 104 of different heights on both sides of the guardrail support frame 101 are overlapped with each other, and fixed with bolts through the corresponding through holes, and the entire device is fixed to the edge of the cantilever platform and spliced. After the initial fixation is completed, the adjustment block 608 is rotated, and the overall rotating round block 604 is pulled outward, and the reset spring 603 is stretched. At the same time, the limit block 606 is pulled out of the groove, and the adjustment block 608 is rotated to be placed horizontally. The rotation of the rotating block 604 is limited to a position after being pulled out, so as to prevent the rotating block 604 from being reset under the action of the reset spring 603. Then, the rotating block 604 is driven to rotate by the extension rod 607, and then the square latch 605 is engaged inside the integrated square groove seat 602 to drive the integrated square groove seat 602 and the connecting shaft 502 fixedly connected thereto to rotate. The rotation of the connecting shaft 502 drives the two first winding wheels 503 and the two second winding wheels 504 to rotate simultaneously, thereby starting to release the wound connecting wire 7.

[0054] At this time, the auxiliary protection structure 4 and the two bottom bracket mechanisms 3 begin to rotate forward and backward respectively until the connecting wire 7 is completely released. At this time, the two bottom bracket mechanisms 3 are placed horizontally to fit the platform, and the overall support connector 302 is installed on the nut seat of the platform through the fixing bolts 304. At the same time, the auxiliary protection structure 4 with the connecting wire 7 released reaches the maximum angle. At this time, the connecting wire 7 is pulled to rotate and pull up the auxiliary protection structure 4, and then the top of the sliding frame 407 is pulled until it slides to the maximum stroke. At this time, the two T-shaped limit rods 410 slide on both sides of the inner wall of the rotating frame 401 until they hit the slide groove blocking cover 403. At this time, the two iron connecting clamps 408 are rotated, and then the clamps are locked. The auxiliary protection structure 4 is engaged on the corresponding fixed card shaft 405, and at the same time, the two corresponding permanent magnet blocks 406 are used to attract the iron connecting card plate 408 to prevent the overall sliding frame 407 from sliding downward, and then the connecting wire 7 is released. The opened auxiliary protection structure 4 rotates to the maximum angle within the limit of the length of the connecting wire 7. The extended auxiliary protection structure 4 can effectively increase the range of the edge protection device and reduce the safety hazard of objects falling from high altitudes. When the auxiliary protection structure 4 is hit by an object, the impact force can be transmitted to the guardrail main body mechanism 1 through the connecting wire 7 and its own structure, and then transmitted to the two bottom bracket mechanisms 3 through the connecting wire 7, thereby ensuring the stability of the entire device when facing impact;

[0055] When the overall protective device is subsequently disassembled, after removing multiple fixing bolts 304 and opening the two iron connecting clamps 408, the rotating round block 604 is driven in the reverse direction to rotate, thereby driving the two first winding wheels 503 and the two second winding wheels 504 to reel in multiple connecting steel wires 7. Until they are completely reeled in, the rotating adjustment block 608 is in a vertical state. Under the action of the reset spring 603, the rotating round block 604 retracts at this time, and the rotating limit block 606 is stuck in the slot to achieve rotation limitation of the rotating round block 604, and then achieve limitation of the connecting shaft 502, to prevent the connecting shaft 502 from rotating and causing the bottom bracket mechanism 3 and the auxiliary protective structure 4 to deflect.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
