Description

Technical Field

[0001] The invention relates to the field of petrochemical storage tanks, and in particular to a modular spliced ​​floating plate of an external floating roof storage tank. Background Art

[0002] An external floating roof tank is an upright cylindrical tank with a floating roof, typically used to store volatile petroleum products such as crude oil, gasoline, or kerosene. The floating roof (also called a float) in an external floating roof tank floats lightly on the surface of the stored liquid, moving freely with the rise and fall of the liquid level.

[0003] CN202358533U discloses a combined external floating plate for a storage tank, which consists of an intermediate floating plate, a cabin and a drainage device. The intermediate floating plate includes a metal frame and an intermediate float. The metal frame includes six main beams, multiple auxiliary beams and a ring beam in a circular form. The six main beams are radially distributed, with a 60-degree angle between two adjacent main beams. One end of the six main beams is simultaneously connected to the ring beam. Multiple auxiliary beams are arranged in parallel. The auxiliary beams are located inside the ring beam and are connected to the ring beam at both ends, thereby forming a mesh-like metal frame. The intermediate float is fixed between two parallel auxiliary beams, at a 60-degree angle to the auxiliary beams, and multiple intermediate floats are arranged in parallel. The intermediate float is made of steel and is connected to the auxiliary beams by welding.

[0004] With respect to the aforementioned combined external float, the drainage device is arranged in the middle of the entire float, and the float is tilted from high to low from the edge to the center. Since the welds formed after welding are uneven, and there are a large number of welds, multiple welds will form a water accumulation area. Although the float is tilted from high to low from the edge to the center, the presence of the water accumulation area will prevent all water in the water accumulation area from flowing to the drainage device. Therefore, after rain, water will remain in the water accumulation area. After long-term use, the middle float will be corroded. In addition, the aforementioned float is constructed by welding the main beam, auxiliary beam, ring beam and middle float inside the storage tank. The entire float is composed of two layers of panels, upper and lower. This structure not only has a very large welding workload and a slow installation speed, but also has a very high cost due to the height of the entire float of 800mm. Summary of the Invention

[0005] The present invention provides a modular splicing floating plate of an external floating roof storage tank, which has the characteristics of fast installation speed and low cost.

[0006] The modular spliced ​​floating plate of the external floating roof storage tank includes multiple groups of spliced ​​buoyancy units, each group of spliced ​​buoyancy units includes multiple buoyancy boxes, multiple first fastening assemblies, at least one launching assembly with an input port, and multiple second fastening assemblies;

[0007] In each group of spliced ​​buoyancy units, both ends of the launching assembly are fastened to the buoyancy box via a first fastening assembly;

[0008] For two adjacent groups of spliced ​​buoyancy units, the buoyancy box in the first group of spliced ​​buoyancy units and the buoyancy box in the second group of spliced ​​buoyancy units are fastened by the second fastening assembly, the launching assembly in the first group of spliced ​​buoyancy units and the buoyancy box in the second group of spliced ​​buoyancy units are fastened by the second fastening assembly, and the launching assembly in the second group of spliced ​​buoyancy units and the buoyancy box in the first group of spliced ​​buoyancy units are fastened by the second fastening assembly.

[0009] In the present invention, the pontoon and the launching assembly are made into a single module. When they need to be assembled into a floating plate, several pontoons and launching assemblies are transported to the site. The pontoons and the launching assembly are fastened by a first fastening assembly and a second fastening assembly to form a floating plate. In this way, a floating plate for an external floating roof storage tank is obtained, which avoids a lot of welding work at the installation site. Not only is the installation speed fast and the construction period short, but also because the height of the entire floating plate is at least 530mm lower than that of the floating plate in the background technology, for external floating roof storage tanks of the same height, the floating plate of the present invention occupies less space. Therefore, the use of the floating plate of the present invention can significantly increase the oil storage capacity in the tank. In addition, each spliced ​​buoyancy unit of the present invention is provided with a launching assembly. On the one hand, when there is water on the surface of the floating plate, the water can flow into the launching assembly. On the other hand, the launching assemblies are dispersedly arranged on the floating plate, so that drainage can be carried out at multiple locations on the floating plate.

[0022] like Figures 1 to 12 As shown, the modular spliced ​​floating plate of the external floating roof tank of the present invention includes multiple groups of spliced ​​buoyancy units FL, each group of spliced ​​buoyancy units FL includes multiple float boxes F, multiple first fastening components E, at least one launching component X with an input port 13a, and multiple second fastening components G. The various parts and the relationship between them are described in detail below.

[0023] like Figure 2 In each set of modular buoyancy units FL, both ends of the launch assembly X are fastened to the buoyancy tank F via first fastening assemblies E. Each buoyancy tank F, when connected to the first fastening assemblies E, forms a drainage channel P1. The inlet 13a of the launch assembly X mates with the drainage channel P1 on the connected buoyancy tank F. When water is present in the drainage channel P1, it flows into the launch assembly X through the inlet 13a. In each set of modular buoyancy units FL, at least two buoyancy tanks F are connected in series via the first fastening assemblies E, forming multiple interconnected drainage channels P1.

[0024] like Figure 2 and Figure 3 In this embodiment, the buoyancy tanks F in each set of modular buoyancy units FL include multiple standard buoyancy tanks BZ. Each standard buoyancy tank BZ comprises a tank body A, an intermediate support body B, a panel C, a first upper connecting plate L1, and a first lower connecting plate L2. The tank body A in each standard buoyancy tank BZ is a rectangular parallelepiped, measuring 3600 mm in length, 1000 mm in width, and 270 mm in height. The tank body A is preferably made of stainless steel. First connecting assemblies D1 for connecting to first fastening assemblies E are provided at both ends of the tank body A.

[0025] like Figure 3 and Figure 4The first connecting component D1 includes a first mounting plate 1 and a first nut 2. The first mounting plate 1 is provided with a first through hole 1a. One end of the first mounting plate 1 is fixed to the box A. The upper end of the box A has an opening, and the lower end of the box A is closed. Preferably, a part of the box A is bent to form the first mounting plate 1, so that the first mounting plate 1 is located above the opening on the box A. The first mounting plate 1 obtained by bending from the box A has good strength. The length of the first mounting plate 1 is much smaller than the length of the box A, and the width of the first mounting plate 1 is smaller than the width of the box A. For example, the length of the first mounting plate 1 is 100 mm, and the width of the first mounting plate 1 is 990 mm.

[0026] like Figure 7 and Figure 8 Each first fastening assembly E includes a first pressure plate 11, a first sealing gasket 12, and a plurality of first bolts 13. In each first fastening assembly E, the number of first pressure plates 11 is one or more, the number of first sealing gaskets 12 can be one or more, and the number of first bolts 13 is multiple. In each set of spliced ​​buoyancy units FL, if the launching assembly X is adjacent to the buoyancy tank F, one end of the first sealing gasket 12 cooperates with the buoyancy tank F, and the other end of the first sealing gasket 12 cooperates with the launching assembly X. The first pressure plate 11 presses on the first sealing gasket 12, and the first bolt 13 passes through one end of the first pressure plate 11 and the first sealing gasket 12 and is threadedly connected to the buoyancy tank F. The first bolt 13 passes through the other end of the first pressure plate 11 and the first sealing gasket 12 and is threadedly connected to the launching assembly X, thereby connecting the buoyancy tank F and the launching assembly X into one body.

[0027] In each group of spliced ​​buoyancy units FL, if the buoyancy box F is adjacent to another buoyancy box F, the first sealing gasket 12 cooperates with the two adjacent buoyancy boxes F, the first pressure plate 11 presses on the first sealing gasket 12, and multiple first bolts 13 pass through the first pressure plate 11 and the first sealing gasket 12 and are threadedly connected to the two adjacent buoyancy boxes F, connecting the two buoyancy boxes into one.

[0028] The other end of the first mounting plate 1 is fixed to the panel C, preferably by welding, forming a step T between the first mounting plate 1 and the panel C. Therefore, when the first fastening assembly E is engaged with the step T, the upper surface of the first pressing plate 11 in the first fastening assembly E is at the same height as the upper surface of the panel C.

[0029] The first nut 2 engages with the first through-hole 1a and is fixed to the first mounting plate 1. After engagement, the centers of the first nut 2 and the first through-hole 1a are aligned. The first nut 2 can be fixed to the first mounting plate 1 by welding or by bonding the first nut 2 to the first mounting plate 1 with an adhesive. In this embodiment, since the step T primarily engages with the first pressure plate 11 in the first fastening assembly E, the first nut 2 is preferably fixed to the lower surface of the first mounting plate 1. This prevents the first nut 2 from occupying the space of the step T. The first bolt 13 sequentially passes through the first pressure plate 11, the first sealing gasket 12, and the first through-hole 1a before being threadedly connected to the first nut 2, thereby fastening the first fastening assembly E to the first mounting plate 1 as a whole. Since the same first fastening assembly E is fixed to the first mounting plates 1 of two adjacent standard buoyancy tanks BZ, the two adjacent standard buoyancy tanks BZ are fastened together by the same first fastening assembly E.

[0030] After panel C is matched with box body A and first connecting component D1, a first accommodating cavity is formed between panel C, box body A and first connecting component D1, and the upper surface of panel C is located above the upper surface of the first connecting component D1. Preferably, the upper surface of panel C is located above the upper surface of the first mounting plate 1.

[0031] The panel C includes a panel body 3, with first lower protrusions 4 protruding from the lower surface of the panel body 3 fixed to each end. The first lower protrusions 4 are secured to the first connecting assembly D1. The left and right ends of the panel body 3 are preferentially bent to form the first lower protrusions 4, respectively. These first lower protrusions 4 are integral with the panel body 3, thus providing superior strength. The first lower protrusions 4 are preferably secured to the first mounting plate 1 of the first connecting assembly D1 by welding.

[0032] The panel body 3 also has a first upper raised portion 5 protruding from its upper surface. The first upper raised portion 5 is secured to the first upper connecting plate L1. The front and rear ends of the panel body 3 are bent to form the first upper raised portion 5. This integral structure of the first upper raised portion 5 and the panel body 3 provides superior strength. The first upper raised portion 5 is preferably secured to the first upper connecting plate L1 by welding.

[0033] Intermediate support B is located within the first accommodating cavity and is connected to box A and panel C. In this embodiment, intermediate support B utilizes a honeycomb core, preferably made of metal, such as stainless steel. Adhesive is applied to the inner bottom of box A and the lower surface of panel C. After intermediate support B is placed within box A, panel C is placed on top. The adhesive secures intermediate support B to box A and secures support B to panel C.

[0034] A first upper connecting plate L1 is disposed on both sides of the first connecting assembly D1. One end of the first upper connecting plate L1 is secured to the upper end of the housing A. The first upper connecting plate L1 is also secured to the panel C and the first connecting assembly D1, respectively. The other end of the first upper connecting plate L1 is located above the upper surface of the panel C. The first upper connecting plate L1 is provided with a plurality of first mounting holes L11 for engaging with the second fastening assembly G. In this embodiment, the first upper connecting plate L1 is integrally formed with the housing A. The first upper connecting plate L1 is preferably secured to the first mounting plate 1 of the first connecting assembly D1 and to the first upper protrusion 5 of the panel C by welding. Based on the above structure, when the first fastening assembly E is connected to the first mounting plate 1, the drainage channel P1 is formed between the first upper connecting plate L1, the panel C, and the first pressure plate 11.

[0035] The first lower connecting plate L2 is secured to the lower end of the housing A. It is provided with a plurality of second mounting holes L21 for engaging with the second fastening assembly G. In this embodiment, the first lower connecting plate L2 has an L-shaped cross-section and is secured to the lower surface of the housing A by welding or adhesive. There are at least four first lower connecting plates L2, arranged along the length and width of the housing A.

[0036] like Figure 7 and Figure 8 For two adjacent groups of spliced ​​buoyancy units FL, the buoyancy tanks F in the first group of spliced ​​buoyancy units FL are fastened to the buoyancy tanks F in the second group of spliced ​​buoyancy units FL via a second fastening assembly G. The second fastening assembly G includes a bolt and a nut. For example, after the bolt in the second fastening assembly G passes through the first mounting holes L11 on the two adjacent first upper connecting plates L1, the bolt is threadedly engaged with the nut in the second fastening assembly G, thereby fastening the two adjacent first upper connecting plates L1 into a single body. Similarly, the second fastening assembly G passes through the second mounting holes L21 on the two adjacent first lower connecting plates L2, thereby fastening the two adjacent first lower connecting plates L2 into a single body, thereby fastening the buoyancy tanks F in the two adjacent groups of spliced ​​buoyancy units FL.

[0037] The aforementioned standard pontoons BZ can be assembled into a rectangular floating platform. Typically, a floating platform is circular. Therefore, when a circular floating platform is desired, non-standard pontoons FB are also required to form the outer circular contour of the floating platform. In this embodiment, the pontoons F in each set of spliced ​​buoyancy units FL also include at least two non-standard pontoons FB. These non-standard pontoons FB are located at the ends of each set of spliced ​​buoyancy units FL and are connected to the standard pontoons BZ or the launching assembly X via a first fastening assembly E.

[0038] The non-standard pontoon FB has different lengths corresponding to different circumferential angles according to the different positions of the corresponding circumferential angles. In this embodiment, the outline of the non-standard pontoon FB is a right-angled trapezoid. Therefore, one of the side surfaces of the non-standard pontoon FB is an inclined surface, and a circular outline is formed by splicing the inclined surfaces on the non-standard pontoon FB.

[0039] The non-standard floating box FB includes a non-standard box body A1, a non-standard panel C1, and an intermediate supporting component B1. The left or right end of the non-standard box body A1 is provided with a second connecting component D2 for connecting to the first fastening component E. The right or left end of the non-standard box body A1 is provided with a mounting plate LB, which is a component of the circular floating plate profile.

[0040] The second connecting component D2 includes a second mounting plate 6 and a second nut 7. The second mounting plate 6 is provided with a second through hole 6a. One end of the second mounting plate 6 is fixed to the non-standard box A1. The lower end of the non-standard box A1 is closed and the upper end has a notch. In this embodiment, a part of the non-standard box A1 is preferably bent to form the second mounting plate 6, so that the second mounting plate 6 is located above the notch. The second mounting plate 6 obtained by bending from the non-standard box A1 has good strength. The length of the second mounting plate 6 is less than the length of the non-standard box A1, and the width of the second mounting plate 6 is less than the width of the non-standard box A1. For example, the length of the non-standard box A1 is 1500mm, the width of the non-standard box A1 is 1000mm, the length of the second mounting plate 6 is 100mm, and the width of the second mounting plate 6 is 990mm.

[0041] After the other end of the second mounting plate 6 is fixed to the non-standard panel C1, the other end of the second mounting plate 6 is preferably fixed to the non-standard panel C1 by welding, and a first step T1 is formed between the second mounting plate 6 and the non-standard panel C1. After the first fastening component E is matched with the first step T1, the upper surface of the first fastening component E and the upper surface of the non-standard panel C1 are located at the same height. In this embodiment, when the first fastening component E is matched with the first step T1, the upper surface of the first pressure plate 11 in the first fastening component E and the upper surface of the non-standard panel C1 are located at the same height.

[0042] The second nut 7 engages with the second through-hole 6a, with the center of the second nut 7 and the center of the second through-hole 6a co-located on a straight line. The second nut 7 is secured to the second mounting plate 6 by welding or by adhesive. In this embodiment, since the first step T1 primarily engages with the first pressure plate 11 and the first sealing gasket 12 of the first fastening assembly E, the second nut 7 is preferentially secured to the lower surface of the second mounting plate 6. This prevents the second nut 7 from occupying the space of the first step T1.

[0043] In the same group of spliced ​​buoyancy units FL, if the standard buoyancy tank BZ is adjacent to the non-standard buoyancy tank FB, a part of the first pressure plate 11 and the first sealing gasket 12 in the first fastening assembly E is matched with the step T, and the other part of the first pressure plate 11 and the first sealing gasket 12 is matched with the first step T1. Then, a part of the first bolt 13 is passed through the first pressure plate 11, the first sealing gasket 12, and the first through hole 1a and is threadedly connected to the first nut 2. The other part of the first bolt 13 is passed through the first pressure plate 11, the first sealing gasket 12, the second through hole 6a and is threadedly connected to the second nut 7, thereby connecting the non-standard buoyancy tank FB and the standard buoyancy tank BZ into one.

[0044] After the non-standard panel C1 is matched with the non-standard box A1 and the second connecting component D2, a second accommodating cavity is formed between the non-standard panel C1, the non-standard box A1 and the second connecting component D2. The upper surface of the non-standard panel C1 is located above the upper surface of the second connecting component D2, and one end of the mounting plate LB is located above the upper surface of the non-standard panel C1.

[0045] The non-standard panel C1 includes a non-standard panel body 8, on which a second lower protrusion 9 is fixed, projecting from the lower surface of the non-standard panel body 8. The second lower protrusion 9 is secured to the second connecting assembly D2. In this embodiment, the second lower protrusion 9 is preferably formed by bending the left or right end of the non-standard panel body 8. This second lower protrusion 9 is integral with the non-standard panel body 8, and the second lower protrusion 9 obtained by bending the non-standard panel C1 has good strength. The second lower protrusion 9 is preferably secured to the second mounting plate 6 of the second connecting assembly D2 by welding.

[0046] A second upper raised portion 10 is fixed to the non-standard panel body 8, protruding from its upper surface. This second upper raised portion 10 is secured to the second upper connecting plate L3 and the mounting plate LB. In this embodiment, the second upper raised portion 10 is formed by bending the front and rear ends of the non-standard panel body 8. This second upper raised portion 10 is integral with the non-standard panel body 8, providing superior strength. The second upper raised portion 10 is preferably secured to the second upper connecting plate L3 and the mounting plate LB by welding.

[0047] The intermediate support component B1 is located within the second accommodating cavity and is connected to the non-standard housing A1 and the non-standard panel C1. In this embodiment, the intermediate support component B1 utilizes a honeycomb core, preferably made of metal, such as stainless steel. An adhesive is applied to the inner bottom surface of the non-standard housing A1 and the lower surface of the non-standard panel C1. After the intermediate support component B1 is placed within the non-standard housing A1, the non-standard panel C1 is placed on top. The adhesive secures the intermediate support component B1 to the non-standard housing A1 and the non-standard panel C1.

[0048] A second upper connecting plate L3 is provided on both sides of the second connecting assembly D2. One end of the second upper connecting plate L3 is secured to the upper end of the non-standard housing A1. The second upper connecting plate L3 is also secured to the non-standard panel C1 and the second connecting assembly D2, respectively. The other end of the second upper connecting plate L3 is positioned above the upper surface of the non-standard panel C1. The second upper connecting plate L3 is provided with a plurality of third mounting holes L31 for engaging with the second fastening assembly G. In this embodiment, the second upper connecting plate L3 is integrally formed with the non-standard housing A1. The second upper connecting plate L3 is preferably secured to the second mounting plate 6 of the second connecting assembly D2 by welding, and the second upper connecting plate L3 is preferably secured to the second upper protrusion 10 of the non-standard panel C1 by welding.

[0049] The second lower connecting plate L4 is secured to the lower end of the non-standard housing A1. The second lower connecting plate L4 is provided with a plurality of fourth mounting holes L41 for engaging with the second fastening assembly G. In this embodiment, the second lower connecting plate L4 has an L-shaped cross-section and is secured to the lower surface of the non-standard housing A1 by welding or adhesive bonding. There are at least four second lower connecting plates L4.

[0050] If the standard buoyancy tank BZ is adjacent to the non-standard buoyancy tank FB in two adjacent sets of spliced ​​buoyancy units FL, bolts from the second fastening assembly G are passed through the first mounting holes L11 on the first upper connecting plate L1 and the third mounting holes L31 on the second upper connecting plate L3, and then connected with nuts to integrally connect the upper ends of the non-standard buoyancy tank FB and the standard buoyancy tank BZ. Furthermore, bolts from the second fastening assembly G are passed through the second mounting holes L21 on the first lower connecting plate L2 and the fourth mounting holes L41 on the second lower connecting plate L4, and then connected with nuts to integrally connect the lower ends of the non-standard buoyancy tank FB and the standard buoyancy tank BZ.

[0051] like Figures 9 to 12 The water discharge assembly X includes a water tank H for water discharge, a third upper connecting plate L5, and a third lower connecting plate L6. The lower end of the water tank H is closed, and the inlet 13a is located at the upper end of the water tank H. A water output component 13b is mounted at the lower end of the water tank H. The output component 13b communicates with the inner cavity of the water tank H and comprises a pipe joint and an intermediate pipe (not shown). One end of the pipe joint is fixed to the water tank H, and the other end is connected to one end of the intermediate pipe. The other end of the intermediate pipe is connected to a water collection tank connected to the bottom of the floating platform. The water collection tank is connected to one end of a main drain pipe (the water collection tank and main drain pipe are not shown in the figure). The other end of the main drain pipe extends to the outside of the external floating roof tank. Water flowing into each water tank H is transferred to the water collection tank through the output component 13b and then discharged to the outside of the external floating roof tank through the main drain pipe. The structure of the water collection tank and main drain pipe is conventional and will not be described in detail here.

[0052] A third connecting assembly D3 for connecting to the first fastening assembly E is provided on both the left and right sides of the upper end of the lower water tank H. The third connecting assembly D3 includes a third mounting plate 14 and a third nut 15 for connecting to the first fastening assembly E. The third mounting plate 14 is fixed to the lower water tank H and is located above the inlet 13a. The third mounting plate 14 is provided with a third through-hole 14a. The third nut 15 engages with the third through-hole 14a and is fixed to the third mounting plate 14.

[0053] Preferably, a portion of the lower water tank H is bent to form the third mounting plate 14, so that the third mounting plate 14 is positioned above the inlet 13a. The third mounting plate 14 formed by bending the lower water tank H has good strength. The width of the third mounting plate 14 is smaller than the width of the lower water tank H, and the length of the third mounting plate 1 is smaller than the width of the lower water tank H. For example, if the length of the lower water tank H is 500 mm and the width of the lower water tank H is 1000 mm, the length of the third mounting plate 14 is 100 mm and the width of the third mounting plate 14 is 990 mm. In this embodiment, each lower water tank H has the same dimensions, i.e., the lower water tank H is a standard tank.

[0054] In this embodiment, the two ends of the launching assembly X are respectively connected to the buoyancy box F through the first fastening assembly E. Since the input port 13a of the launching assembly X and the drainage channel P1 cooperate, when there is water in the drainage channel P1, the water in the drainage channel P1 flows into the launching assembly X.

[0055] like Figure 10 In the same group of spliced ​​buoyancy units FL, if the standard buoyancy tank BZ is adjacent to the lower water tank H, then a portion of the first pressure plate 11 and the first sealing gasket 12 in the first fastening assembly E is matched with the step T, and the other portion of the first pressure plate 11 and the first sealing gasket 12 is matched with the third mounting plate 14. Then, a portion of the first bolt 13 is passed through the first pressure plate 11, the first sealing gasket 12, and the first through hole 1a and is threadedly connected to the first nut 2. The other portion of the first bolt 13 is passed through the first pressure plate 11, the first sealing gasket 12, the third through hole 14a and is threadedly connected to the third nut 15, thereby connecting the lower water tank H and the standard buoyancy tank BZ in the launching assembly X as one.

[0056] like Figure 10 In the same group of spliced ​​buoyancy units FL, if the non-standard float tank FB is adjacent to the lower water tank H, then the first pressure plate 11 and a portion of the first sealing gasket 12 in the first fastening assembly E are matched with the first step T1, and the other portion of the first pressure plate 11 and the first sealing gasket 12 are matched with the third mounting plate 14. Then, a portion of the first bolt 13 is passed through the first pressure plate 11, the first sealing gasket 12, and the second through hole 6a and is threadedly connected to the second nut 7. The other portion of the first bolt 13 is passed through the first pressure plate 11, the first sealing gasket 12, and the third through hole 14a and is threadedly connected to the third nut 15, thereby connecting the lower water tank H and the non-standard float tank FB in the launching assembly X into one.

[0057] In two adjacent groups of spliced ​​buoyancy units FL, the launching assembly X in the first group of spliced ​​buoyancy units FL and the buoyancy box F in the second group of spliced ​​buoyancy units FL are fastened by the second fastening assembly G, and the launching assembly X in the second group of spliced ​​buoyancy units FL and the buoyancy box F in the first group of spliced ​​buoyancy units FL are fastened by the second fastening assembly G.

[0058] The third connecting assembly D3 is provided with a third upper connecting plate L5 on both sides. One end of the third upper connecting plate L5 is fixed to the upper end of the lower water tank H, and the other end of the third upper connecting plate L5 is located above the upper surface of the third connecting assembly D3. The third upper connecting plate L5 is provided with a plurality of fifth mounting holes L51 for engaging with the second fastening assembly G. In this embodiment, the third upper connecting plate L5 is integrally formed with the lower water tank H and is perpendicular to the third mounting plate 14.
