Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting pipes, in particular to a detachable bracket for a main water-transformer spray fire-fighting water pipe. Background Art

[0002] Power plants often have oil-immersed transformers of 90MV·A and above, and substations often have oil-immersed transformers of 125MV·A and above. According to the requirements of the "Code for Fire Protection Design of Buildings", oil-immersed transformers in power plants with a single capacity of 90MV·A and above, and oil-immersed transformers in independent substations with a single capacity of 125MV·A and above, need to be equipped with water spray or oil drainage and nitrogen injection systems.

[0003] In actual operation at power plants or substations, oil-drainage and nitrogen-injection fire extinguishing systems are less effective than water spray systems. Therefore, water spray systems are currently the preferred fire extinguishing system for large-capacity main transformers. Since main transformer fire extinguishing systems are typically located at a high altitude, firefighting piping must be elevated on multiple levels or the main transformer fire extinguishing system itself must serve as a support for the pipes. However, the fixed supports typically used for main transformer water spray firefighting pipes, coupled with their high location, hinder subsequent maintenance of the main transformer water spray fire extinguishing system. Utility Model Content

[0004] The purpose of the utility model is to provide a detachable bracket for a main transformer water spray fire water pipe, so as to solve the problem of inconvenience in repairing the main transformer water spray fire pipe and improve the efficiency of maintaining the main transformer water spray fire extinguishing system.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] A detachable bracket for a main variable water spray fire extinguishing water pipe comprises a vertical rod and an L-shaped block for supporting the pipe, and a support plate arranged at the top of the main variable water spray fire extinguishing system, the support plate contacts the bottom of the pipe, the L-shaped block comprises a horizontal brace and a vertical brace, the horizontal brace is provided with a first nut and a first clamp in contact with the pipe, the two ends of the first clamp are respectively passed through the horizontal brace and threadedly connected to the first nut; the vertical brace is provided with a second nut and several second clamps in contact with the vertical rod, the two ends of the second clamp are respectively passed through the horizontal brace and threadedly connected to the second nut, a fixing plate slidably arranged at the end of the second clamp is provided between the second nut and the vertical brace, a slide is slidably connected to the vertical brace, one side of the slide is provided with several wedge blocks, the fixing plate is provided with a groove, and one side of the wedge block is provided with an inclined surface in contact with the groove.

[0007] Furthermore, a groove is provided on the vertical support, a ball bearing is slidably connected to the slide plate, and a return spring is provided between the ball bearing and the slide plate.

[0008] Furthermore, a screw is threadedly connected to the slide plate, and an end of the screw is in contact with the ball.

[0009] Furthermore, the end of the screw extends to the outside of the skateboard and is provided with a handle.

[0010] Furthermore, a first friction plate is provided on one side of several second hoops, a second friction plate is provided on one side of the vertical support, and several protrusions in contact with the vertical rod are respectively provided on the first friction plate and the second friction plate.

[0011] Furthermore, it also includes a base, the end of the base is provided with a first flange, and the end of the vertical rod is provided with a second flange used in conjunction with the first flange.

[0012] Furthermore, a plurality of reinforcing plates are provided on the base.

[0013] Furthermore, a third nut and a third clamp in contact with the pipe are provided on the support plate, and both ends of the third clamp are respectively passed through the cross brace and are threadedly connected to the third nut.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Before fixing the pipe, place several L-shaped blocks on one side of the vertical rod in sequence. Through the coordination between the vertical support, vertical rod, second clamp, fixing plate, second nut, groove, slide plate and wedge block, several L-shaped blocks can be slid onto the vertical rod to facilitate the actual adjustment of the fixing height according to the actual needs, thereby improving the efficiency of pipe installation.

[0016] 2. When it is necessary to fix the pipeline, the two ends of the pipeline are pre-connected with the corresponding equipment respectively, and the L-shaped block is slid on the vertical rod at the same time so that several cross braces are in contact with the pipeline respectively. Then, the pipeline is fixed on the L-shaped block through the cooperation between the first clamp, the pipeline, the cross brace, and the first nut; then, through the cooperation between the vertical support, the slide plate, the wedge block, and the inclined surface, the several fixing plates are driven to move outward at the same time and further contact the second nut. Since the second nut is threadedly connected to the second clamp, the several second clamps are driven to move toward one side of the vertical support, increasing the friction between the several second clamps and the vertical rod, thereby fixing the L-shaped block on the vertical rod. In addition, by adjusting the position of the second nut on the second clamp, the tightness of different second clamps can be adjusted, thereby compensating for the errors caused by the manufacturing process of different second clamps, making the several second clamps fix the L-shaped block more firmly, and further improving the stability of fixing the pipeline;

[0017] 3. When maintenance or replacement of pipelines is required, the connection between the two ends of the pipeline and the corresponding equipment is released, and the restriction of the wedge block on the sliding of the fixed plate is released by sliding the corresponding slide plate downward, thereby reducing the friction between the second clamp and the vertical rod, allowing the L-shaped block to slide relative to the vertical rod, and then the pipeline is moved down to a lower height to facilitate the detection of whether the pipeline has any leakage. When the pipeline needs to be replaced, the first clamp on the corresponding cross brace is removed by screwing the corresponding first nut, thereby releasing the L-shaped block from fixing the pipeline. There is no need to maintain and replace the pipeline at a high place, which improves the efficiency of maintaining the main transformer water spray fire extinguishing system. In addition, the bracket can still be recycled after maintenance, reducing the manufacturing cost required to make the bracket. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0031] A detachable bracket for main water-spray fire-fighting water pipes, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, it includes a vertical rod 1 and an L-shaped block 3 for supporting a pipe 2, and a support plate 5 provided on the top of a main variable water spray fire extinguishing system 4. The support plate 5 contacts the bottom of the pipe 2 and supports the root of the pipe 2 through the support plate 5. The L-shaped block 3 includes a horizontal support 6 and a vertical support 7. The horizontal support 6 is provided with a first nut 8 and a first clamp 9 in contact with the pipe 2. The two ends of the first clamp 9 are respectively passed through the horizontal support 6 and are threadedly connected to the first nut 8. By rotating the first nut 8, it is brought into contact with the horizontal support 6, and then the first nut 8 is further tightened. , driving the first clamp 9 to move until it contacts the pipe 2, and the friction between the first clamp 9 and the pipe 2 limits the left and right movement of the pipe 2. The first clamp 9 and the cross brace 6 are respectively in contact with the side of the pipe 2 to limit the movement of the pipe 2 on the L-shaped block 3, thereby fixing the pipe 2 on the L-shaped block 3; the vertical support 7 is provided with a second nut 10 and a plurality of second clamps 11 in contact with the vertical rod 1, and the two ends of the second clamp 11 pass through the cross brace 6 and are threadedly connected to the second nut 10, and the second nut 10 and the vertical support 7 are connected. A fixing plate 12 is provided which is slidably arranged at the end of the second hoop 11. A slide plate 13 is slidably connected to the vertical support 7. One side of the slide plate 13 is provided with a plurality of wedge blocks 14. A groove 15 is provided on the fixing plate 12. One side of the wedge block 14 is provided with an inclined surface 16 in contact with the groove 15. The slide plate 13 is slid on the vertical support 7 so that the plurality of wedge blocks 14 provided on one side thereof are further in contact with the inclined surface 16. The component force generated after the contact will drive the plurality of fixing plates 12 to move outward at the same time and further contact with the second nut 10. Since the second nut 10 is threadedly connected to the second clamp 11, the plurality of second clamps 11 are driven to move toward one side of the vertical support 7, thereby increasing the friction between the plurality of second clamps 11 and the vertical rod 1, thereby fixing the L-shaped block 3 on the vertical rod 1. In addition, by adjusting the position of the second nut 10 on the second clamp 11, the tightness of different second clamps 11 can be adjusted, thereby compensating for the errors caused by the manufacturing process of different second clamps 11, making the plurality of second clamps 11 fix the L-shaped block 3 more firmly, further improving the stability of fixing the pipe 2;

[0032] In addition, when the pipeline 2 needs to be maintained or replaced, the connection between the two ends of the pipeline 2 and the corresponding equipment is released, and the restriction of the wedge block 14 on the sliding of the fixed plate 12 is released by sliding the corresponding slide plate 13 downward, thereby reducing the friction between the second clamp 11 and the vertical rod 1, so that the L-shaped block 3 can slide relative to the vertical rod 1, and then the pipeline 2 is moved down to a lower height to facilitate the detection of whether the pipeline 2 has leaks. When the pipeline 2 needs to be replaced, the first clamp 9 on the corresponding cross brace 6 is removed by screwing the corresponding first nut 8, thereby releasing the fixation of the L-shaped block 3 on the pipeline 2. There is no need to maintain and replace the pipeline 2 at a higher place, thereby improving the efficiency of maintaining the main transformer water spray fire extinguishing system 4; in addition, the bracket can still be recycled after maintenance, reducing the manufacturing cost required to make the bracket.

[0033] Preferably, Figure 5 and Figure 6 As shown, a groove 17 is provided on the vertical support 7, and a ball 18 is slidably connected to the slide 13. A return spring 19 is provided between the ball 18 and the slide 13. The resistance generated by the contact between the ball 18 and the groove 17 can avoid the slide 13 from being accidentally driven to slide on the vertical support 7, further improving the stability of the pipe 2 fixation, thereby extending the service life of the main variable water spray fire extinguishing system 4. In addition, when it is necessary to slide the L-shaped block 3 on the vertical rod 1, an external force is applied to the slide 13. When the external force is greater than the resistance generated by the return spring 19, the component force generated by the contact between the ball 18 and the groove 17 will drive the ball 18 to move to the right and compress the return spring 19, so that the slide 13 can slide relative to the vertical support 7, which is convenient for subsequently moving the pipe 2 to a lower place, thereby improving the efficiency of maintaining the main variable water spray fire extinguishing system 4.

[0034] Preferably, Figure 5 and Figure 6 As shown, the slide plate 13 is threadedly connected with a screw rod 20, and the end of the screw rod 20 is in contact with the ball 18. After the L-shaped block 3 is fixed on the vertical rod 1, the screw rod 20 is rotated on the slide plate 13 to move on the slide plate 13 until the end of the screw rod 20 is in contact with the ball 18. The resistance generated after the two are released further restricts the movement of the ball 18 to the right, preventing the slide plate 13 from sliding on the vertical support 7 after being subjected to a pressure greater than that generated by the return spring 19, further improving the stability of the fixed pipe 2 and extending the service life of the main variable water spray fire extinguishing system 4.

[0035] Preferably, Figure 5 and Figure 6 As shown, the end of the screw rod 20 extends to the outside of the slide plate 13 and is provided with a handle 21 to facilitate the rotation of the screw rod 20 and simplify the operation steps of removing the pipeline 2, thereby improving the efficiency of maintaining the main water spray fire extinguishing system 4.

[0036] Preferably, Figure 7 and Figure 8 As shown, a first friction plate 22 is provided on one side of several second clamps 11, and a second friction plate 23 is provided on one side of the vertical support 7. The first friction plate 22 and the second friction plate 23 are respectively provided with a plurality of protrusions 24 that contact the vertical rod 1, thereby increasing the contact area between the second clamp 11 and the L-shaped block 3 and the vertical rod 1, thereby increasing the friction force between the L-shaped block 3 and the vertical rod 1, better fixing the pipe 2 on the vertical rod 1, further improving the stability of the fixed pipe 2, and extending the service life of the main transformer water spray fire extinguishing system 4.

[0037] Preferably, Figure 1 and Figure 4As shown, it also includes a base 25, and the end of the base 25 is provided with a first flange 26, and the end of the vertical rod 1 is provided with a second flange 27 used in conjunction with the first flange 26. Specifically, the first flange 26 and the second flange 27 are detachably connected by bolts. When the entire pipeline 2 needs to be replaced, the bolts connecting the first flange 26 and the second flange 27 at the bottom can be removed, which facilitates the subsequent disassembly of the entire pipeline 2 and improves the efficiency of maintaining the main variable water spray fire extinguishing system 4.

[0038] Preferably, Figure 4 As shown, the base 25 is provided with a plurality of reinforcing plates 28 to increase the stability of the connection between the base 25 and the ground and improve the effect of fixing the pipeline 2.

[0039] Preferably, Figure 2 As shown, the support plate is provided with a third nut 29 and a third clamp 30 in contact with the pipe 2. The two ends of the third clamp 30 pass through the cross brace 6 and are threadedly connected to the third nut 29, so that the root of the pipe 2 can be detachably fixed on the support plate 5, which is convenient for subsequent disassembly of the pipe 2 and improves the efficiency of maintaining the main transformer water spray fire extinguishing system 4.

[0040] Example 1

[0041] The utility model provides a detachable bracket for a main water-transformer spray fire-fighting water pipe, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, before fixing the pipe 2, several L-shaped blocks 3 are placed on one side of the vertical rod 1 in sequence, so that the vertical support 7 is in contact with the vertical rod 1, and then the two ends of the second clamp 11 are respectively passed through the vertical support 7 and the fixing plate 12 and are threadedly connected with the second nut 10, and the fixing plate 12 is slid toward the side of the vertical support 7 so that the groove 15 on the fixing plate 12 is in contact with the wedge block 14 provided on the side of the slide plate 13, and at the same time, the second clamp 11 is slid toward the side of the vertical support 7 so that the second clamp 11 is in contact with the vertical rod 1, and then the second nut 10 is rotated on the second clamp 11 so that the second nut 10 is in contact with the fixing plate 12, thereby sliding several L-shaped blocks 3 on the vertical rod 1, which is convenient for adjusting the fixed height according to actual needs and improving the efficiency of installing the pipe 2;

[0042] When it is necessary to fix the pipe 2, the two ends of the pipe 2 are connected to the corresponding equipment in advance, and the L-shaped block 3 is slid on the vertical rod 1 at the same time, so that several cross braces 6 are in contact with the pipe 2 respectively. Then, the first clamp 9 is placed on the outside of the pipe 2, and its two ends are respectively passed through the cross braces 6 and threadedly connected with the first nut 8. By rotating the first nut 8, it is in contact with the cross brace 6, and then the first nut 8 is further tightened to drive the first clamp 9 to move until it is in contact with the pipe 2. The friction between the first clamp 9 and the pipe 2 limits the left and right movement of the pipe 2. The first clamp 9 and the cross brace 6 are in contact with the side of the pipe 2 respectively, limiting the movement of the pipe 2 on the L-shaped block 3, thereby fixing the pipe 2 on the L-shaped block 3; finally, slide the slide 13 on the vertical brace 7 , so that the several wedge blocks 14 provided on one side thereof are further in contact with the inclined surface 16. The component force generated after the contact will drive the several fixing plates 12 to move outward at the same time and further contact with the second nut 10. Since the second nut 10 is threadedly connected to the second clamp 11, the several second clamps 11 are driven to move toward one side of the vertical support 7, thereby increasing the friction between the several second clamps 11 and the vertical rod 1, and then fixing the L-shaped block 3 on the vertical rod 1. In addition, by adjusting the position of the second nut 10 on the second clamp 11, the tightness of different second clamps 11 can be adjusted, thereby compensating for the errors generated in the manufacturing process of different second clamps 11, making the several second clamps 11 fix the L-shaped block 3 more firmly, further improving the stability of the fixed pipe 2;

[0043] When the pipeline 2 needs to be maintained or replaced, the connection between the two ends of the pipeline 2 and the corresponding equipment is released, and the restriction of the wedge block 14 on the sliding of the fixed plate 12 is released by sliding the corresponding slide plate 13 downward, thereby reducing the friction between the second clamp 11 and the vertical rod 1, so that the L-shaped block 3 can slide relative to the vertical rod 1, and then the pipeline 2 is moved down to a lower height to facilitate the detection of whether the pipeline 2 has leaks. When the pipeline 2 needs to be replaced, the first clamp 9 on the corresponding cross brace 6 is removed by screwing the corresponding first nut 8, thereby releasing the fixation of the L-shaped block 3 on the pipeline 2. There is no need to maintain and replace the pipeline 2 at a higher place, thereby improving the efficiency of maintaining the main transformer water spray fire extinguishing system 4; in addition, the bracket can still be recycled after maintenance, reducing the manufacturing cost required to make the bracket.

[0044] Example 2

[0045] Based on Example 1, Figure 5 and Figure 6As shown, it is necessary to slide the L-shaped block 3 on the vertical rod 1. When maintaining the pipe 2, an external force is applied to the slide plate 13. When the external force is greater than the resistance generated by the return spring 19, the component force generated by the contact between the ball 18 and the groove 17 will drive the ball 18 to the right and compress the return spring 19, allowing the slide plate 13 to slide relative to the vertical support 7, facilitating the subsequent movement of the pipe 2 to a lower position and improving the efficiency of maintaining the main water spray fire extinguishing system 4;

[0046] After the maintenance of the pipeline 2 is completed and the L-shaped block 3 needs to be fixed on the vertical rod 1, the screw 20 is rotated on the slide 13 to move it on the slide 13 until the end of the screw 20 contacts the ball 18. The resistance generated after the two are released further limits the movement of the ball 18 to the right, and the resistance generated after the ball 18 contacts the groove 17 can prevent the slide 13 from sliding on the vertical support 7 after being subjected to a pressure greater than that generated by the return spring 19, thereby further improving the stability of the fixed pipeline 2 and extending the service life of the main transformer water spray fire extinguishing system 4.

[0047] Example 3

[0048] Based on Example 1, Figure 1 and Figure 4 As shown, it also includes a base 25, and a first flange 26 is provided at the end of the base 25, and a second flange 27 is provided at the end of the vertical rod 1 for use with the first flange 26. Specifically, the first flange 26 and the second flange 27 are detachably connected by bolts. When the entire pipeline 2 needs to be replaced, the bolts connecting the first flange 26 and the second flange 27 at the bottom can be removed, which facilitates the subsequent disassembly of the entire pipeline 2 and improves the efficiency of maintaining the main variable water spray fire extinguishing system 4. In addition, a number of reinforcing plates 28 are provided on the base 25 to increase the stability of the connection between the base 25 and the ground, thereby improving the effect of fixing the pipeline 2.
