Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and particularly relates to a cable connection structure for a photovoltaic bracket. Background Art

[0002] Photovoltaic power generation, as a clean, safe and renewable energy technology, is developing rapidly worldwide. However, in complex terrains or special scenarios, the application of traditional rigid photovoltaic brackets is restricted. Flexible photovoltaic brackets have emerged. With their characteristics of large span, high adaptability and flexible installation, they provide a better solution for photovoltaic power generation projects. Different from traditional rigid photovoltaic brackets, flexible photovoltaic brackets adopt a tension structure system design with both ends fixed, and use cables as component support members to form a large-span photovoltaic module support structure. Flexible photovoltaic brackets are usually used in conjunction with a cable connection structure. The two ends of the cable are connected to the bracket through fastening components. This design can effectively enhance the stability of the system, improve the wind resistance and seismic resistance of the photovoltaic power station, and ensure the safety and long-term reliability of the photovoltaic system under various environmental conditions.

[0003] In the existing cable connection structure for photovoltaic brackets, for example, a cable structure and its usage method for a flexible photovoltaic bracket disclosed in the Chinese patent application document with the publication number CN119276194A. The cable structure of this flexible photovoltaic bracket is provided with a third fixing block, a third cable and a support component. After the photovoltaic panel is fixed on the first cable and the second cable through a snap component, at this time, with the cooperation of the third fixing block, the third cable and the support component, the lower end of the photovoltaic panel can be supported, so that the stress on the first cable and the second cable can be reduced, thereby increasing the service life of the first cable and the second cable. At the same time, it also makes the photovoltaic panel more stable during installation, thereby reducing the shaking amplitude of the photovoltaic panel. When fixing the photovoltaic panel, after the second wedge block contacts the first wedge block, the second wedge block will squeeze the first wedge block to move, and then with the cooperation of the limit groove and the limit block, the pressing plate can be stably moved closer to the clamping plate, and then with the cooperation of the clamping plate, the fixing of the photovoltaic panel can be realized, making the installation of the photovoltaic panel more convenient and fast.

[0004] However, during the use of the above-mentioned cable structure of the flexible photovoltaic bracket in the prior art, the entire cable is fixed to the support frame as a whole through a fixing block. Since the cable is composed of multiple steel wires twisted together, when one of the steel wires in the twisted structure breaks or is damaged, it is easy to cause the fixing force of the fixing block on the entire cable to decrease, the fixing reliability to decrease, thereby causing loosening or failure of the fixing point, and even causing the cable to fall off, endangering the safety of the photovoltaic bracket. Summary of the Invention

[0005] The present invention provides a cable connection structure for a photovoltaic support, aiming to solve the problem in the related art that when a single steel wire rope in the cable structure of a flexible photovoltaic support breaks or is damaged, it is likely to cause a decrease in the fixing force of the fixing block on the entire cable.

[0006] The cable connection structure for a photovoltaic support provided by the present invention adopts the following technical solution:

[0007] A cable connection structure for a photovoltaic support, used to install the end of a cable on a support frame, includes:

[0008] A fixed seat, which is arranged on the support frame. The fixed seat has a tapered chamber with a larger left end and a smaller right end. The left and right ends of the tapered chamber are respectively communicated with the outside, and form a passing end for passing out the steel wire rope and a penetrating end for penetrating the cable.

[0009] A fastener, which is assembled on the fixed seat to move left and right. The fastener includes a tapered plug that cooperates with the tapered chamber and a plurality of partition rods arranged on the left end face of the tapered plug. There is an extrusion space between the outer side wall of the tapered plug and the inner side wall of the tapered chamber. The cable penetrates into the tapered chamber from the penetrating end and is divided into multiple steel wire ropes that pass through the extrusion space, and then pass out of the tapered chamber through the passing end. Each of the partition rods is inserted between adjacent two steel wire ropes to separate the steel wire ropes in the cable.

[0010] A locking member, which is arranged on the fixed seat and connected to the fastener. The locking member is used to drive the fastener to move rightward, so as to push the tapered plug into the tapered chamber, thereby enabling the tapered plug to cooperate with the tapered chamber to tightly fix the steel wire rope.

[0011] By adopting the above technical solution, a fastener and a locking member are arranged on the fixed seat. The end of the stranded cable is spread out to form multiple steel wire ropes, and the multiple steel wire ropes enter the extrusion space formed between the tapered plug and the tapered chamber. The steel wire ropes are independently separated by the partition rods, and the tapered plug is pushed into the tapered chamber by the locking member, so that the tapered plug cooperates with the tapered chamber to tightly fix the steel wire ropes. In this way, it can be ensured that each steel wire rope exists independently in the extrusion space and independently receives the extrusion force from the outer side wall of the tapered plug and the inner side wall of the tapered chamber, thereby independently fixing each steel wire rope. Even if a certain steel wire rope breaks or is damaged, it will not affect the fixing effect of other steel wire ropes, avoiding the overall fixing failure caused by the breakage of a single steel wire rope, and improving the reliability and safety of the entire cable connection mechanism.

[0012] Furthermore, the locking member includes a locking ring installed on the fixed seat and located on the left side of the fastener, and a locking elastic member connected between the locking ring and the fastener. The locking elastic member is used to apply an elastic force to the fastener to make the fastener move rightward.

[0013] With the above technical solution, the elastic force locking method can provide continuous pressure to prevent loosening, and is fast and simple.

[0014] Furthermore, the fastener further includes a connecting ring connected between a plurality of partition rods and extending circumferentially along the conical plug, and a plurality of the locking elastic members are distributed circumferentially along the connecting ring between the connecting ring and the locking ring.

[0015] Furthermore, the cable connection structure of the photovoltaic support further includes a driving gear rotatably mounted on the fixed seat. A driven gear cooperating with the driving gear and a clamping groove cooperating with the connecting ring are provided on the locking ring. The connecting ring is movably assembled on the locking ring through a clamping block with left and right guiding and circumferential limiting along the connecting ring to rotate synchronously with the locking ring.

[0016] With the above technical solution, it is used to realize the rotation of the fastener. When the fastener rotates, it can drive the steel wire rope to rotate around the central axis of the conical plug through the rope threading buckle, so as to further untie the stranded part of the steel cable, which is convenient for subsequent tensioning adjustment.

[0017] Furthermore, the fixed seat further has a horizontal pipe section located on the right side of the conical chamber. The penetrating end of the conical chamber communicates with the outside through the horizontal pipe section. The cable connection structure of the photovoltaic support further includes a fixing mechanism installed at the horizontal pipe section. The fixing mechanism includes a plurality of arc-shaped lock pieces distributed circumferentially along the horizontal pipe section and a driver corresponding to each arc-shaped lock piece for driving each arc-shaped lock piece to move radially along the horizontal pipe section. Each of the arc-shaped lock pieces is arc-shaped and has a pressing surface for fitting the outer surface of the steel cable. When the driver drives the arc-shaped lock piece to approach the steel cable radially along the horizontal pipe section, the pressing surface of the arc-shaped lock piece can abut against the outer surface of the steel cable.

[0018] Furthermore, the cable connection structure of the photovoltaic support further includes an assembly column coaxially arranged with the driving gear, and an assembly groove is formed on the assembly column.

[0019] Furthermore, each of the drivers includes a screw rod rotatably connected to the arc-shaped lock piece and a knob provided at one end of the screw rod away from the arc-shaped lock piece. The fixed seat is provided with threaded holes corresponding to the screw rods and threadedly connected to the screw rods at the horizontal pipe section.

[0020] With the above technical solution, the staff can rotate the knob, and the knob drives the screw rod to rotate, so that the arc-shaped lock piece approaches or moves away from the steel cable radially along the horizontal pipe section, thereby locking or unlocking the stranded state of the steel cable at the fixing mechanism.

[0021] Further, the fastener further includes a plurality of rope threading buckles circumferentially arranged on the conical plug along the circumferential direction of the conical plug. Each of the rope threading buckles is located between two adjacent partition rods and includes two legs movably assembled in the conical plug along the radial direction of the conical plug and a head connected between the two adjacent legs. The head is located in the extrusion space, and a through hole for passing a steel wire rope is formed on the side surface facing the outer side wall of the conical plug.

[0022] With the above technical solution, the rope threading buckle is used to guide each steel wire rope in the steel cable through the extrusion space to ensure that the steel wire rope can accurately enter the predetermined position during the installation process, avoiding fixing failure caused by the deviation or winding of the steel wire rope. In addition, the outer side surface of the head of the rope threading buckle can receive the extrusion force from the inner side wall of the conical chamber and transmit it to the steel wire rope in the through hole, thereby firmly fixing the steel wire rope in the extrusion space and further improving the fixing reliability.

[0023] Further, the fastener further includes a converging ring arranged on the left side of the plurality of partition rods and fixedly connected to the partition rods. The converging ring is used to converge the steel wire ropes passing out of the conical chamber through the passing-out end.

[0024] With the above technical solution, the converging ring can cooperate with the part of the steel cable that remains in a stranded state at the passing-in end, so that the steel wire ropes at both axial ends of the conical plug have a tendency to converge towards the central axis of the conical plug, which is beneficial to guiding the steel wire ropes in the extrusion space to closely fit the outer side wall of the conical plug, thereby improving the fastening effect.

[0025] Further, the steel cable connection structure of the photovoltaic bracket further includes a clamp arranged on the fixed seat and on the left side of the fastener. The clamp includes two clamp bodies that are opposite to each other front and back and are movably assembled on the fixed seat in the front and back directions. The opposite side surfaces of the two clamp bodies form a clamp groove for receiving the steel wire rope. A converging spring is arranged between each clamp body and the fixed seat. The converging spring is used to apply an elastic force to the clamp body so that the two clamp bodies approach each other, thereby closing the two clamp grooves to receive the steel wire rope. One end of the clamp groove away from the fastener extends outward to form a docking head.

[0026] The beneficial effects of a steel cable connection structure of a photovoltaic bracket provided by the present invention are:

[0027] 1. Set a fastener and a locking member on the fixed seat. Spread the end of the stranded steel cable to form multiple steel wire ropes, and make the multiple steel wire ropes enter the extrusion space formed between the tapered plug and the tapered chamber. Independently separate the steel wire ropes through a separating rod, and push the tapered plug into the tapered chamber through the locking member, so that the tapered plug cooperates with the tapered chamber to tightly fix the steel wire ropes. This can ensure that each steel wire rope exists independently in the extrusion space and is independently subjected to the extrusion force from the outer wall of the tapered plug and the inner wall of the tapered chamber, thereby independently fixing each steel wire rope. Even if a certain steel wire rope breaks or is damaged, it will not affect the fixing effect of other steel wire ropes, avoiding the overall fixing failure caused by the breakage of a single steel wire rope, and improving the reliability and safety of the entire steel cable connection mechanism. In addition, independently fixing each steel wire rope can also make each steel wire rope receive uniform pressure, better transmit and disperse stress during fastening, and enhance the connection strength between the steel cable and the fixed seat.

[0028] 2. Set a driving gear, a fixing mechanism and a clamping device on the fixed seat. Lock the stranded state of the steel cable at the horizontal pipe section through the fixing mechanism, and then drive the locking ring to rotate through the driving gear, so that the locking ring drives the fastener to rotate. When the fastener rotates, further untie the stranded part of the steel cable. Then, the clamping device can be connected to the tensioning machine, and the tensioning machine is used to tension the steel cable, realizing the tensioning adjustment function after fixing, and improving the versatility and flexibility of the steel cable connection structure of the photovoltaic bracket.

DETAILED DESCRIPTION

[0038] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0039] like Figures 1 to 7 As shown, and refer to Figure 1 As shown in the figure, the embodiment of the photovoltaic support cable connection structure of the present invention is used to install the end of the cable 90 on the support frame 10, including a fixing seat 20, a fastener 30, a locking member 40, a driving gear 50, a fixing mechanism 60, a clamp 70 and a protective cover 80. Among them, the fixing seat 20 is fixed on the support frame 10, and the fastener 30, the locking member 40, the driving gear 50, the fixing mechanism 60, the clamp 70 and the protective cover 80 are respectively installed on the fixing seat 20. The fastener 30 and the locking member 40 can cooperate with each other to fix the end of the cable 90 on the fixing seat 20, the driving gear 50, the fixing mechanism 60 and the clamp 70 can cooperate with each other to tension the cable 90, and the protective cover 80 is provided on the outside of the fastener 30, the locking member 40, the driving gear 50, the fixing mechanism 60 and the clamp 70 to protect the internal components and prevent accidental contact.

[0040] like Figure 2 and Figure 6As shown, the fixed seat 20 and the support frame 10 are integrally formed. The fixed seat 20 has a tapered chamber 210 that is larger on the left and smaller on the right, and a horizontal pipe section 220 located on the right side of the tapered chamber 210. The left and right ends of the tapered chamber 210 respectively form a passing end 212 for passing out the steel wire rope 910 and a penetrating end 211 for penetrating the steel cable 90. The passing end 212 of the tapered chamber 210 communicates with the outside, and the penetrating end 211 of the tapered chamber 210 communicates with the outside through the horizontal pipe section 220. Installation frames 230 extending forward and backward are respectively arranged on the front and rear sides of the fixed seat 20, and sliders 231 are movably assembled back and forth in each installation frame 230.

[0041] As Figures 2 to 5 shown, the fastener 30 is movably assembled left and right on the fixed seat 20. The fastener 30 includes a tapered plug 310 that cooperates with the tapered chamber 210, a plurality of partition rods 320 fixed to the left end face of the tapered plug 310, a connecting ring 330 connected between the plurality of partition rods 320 and extending circumferentially along the tapered plug 310, a converging ring 350 fixed to the left side of the plurality of partition rods 320 through a fixing rod 360, and a plurality of rope passing buckles 340 arranged circumferentially on the tapered plug 310 along the tapered plug 310.

[0042] There is an extrusion space between the outer side wall of the tapered plug 310 and the inner side wall of the tapered chamber 210. The steel cable 90 is inserted into the fixed seat 20 through the horizontal pipe section 220, penetrates into the tapered chamber 210 from the penetrating end 211, and then is divided into a plurality of steel wire ropes 910 to pass through the extrusion space, and then passes out of the tapered chamber 210 through the passing end 212.

[0043] The steel cable 90 in the embodiment is formed by stranding four steel wire ropes 910. Correspondingly, the number of partition rods 320 is set to four. Each partition rod 320 is inserted between adjacent two steel wire ropes 910 to separate the steel wire ropes 910 in the steel cable 90, avoid the steel wire ropes 910 from winding or aggregating with each other, ensure that each steel wire rope 910 exists independently in the extrusion space, and is independently subjected to the extrusion force from the outer side wall of the tapered plug 310 and the inner side wall of the tapered chamber 210, so as to independently fix each steel wire rope 910. Even if a certain steel wire rope 910 breaks or is damaged, it will not affect the fixing effect of other steel wire ropes 910, avoid the overall fixing failure caused by the breakage of a single steel wire rope 910, and improve the reliability and safety of the entire steel cable connection mechanism. In addition, fixing each steel wire rope 910 independently can also make each steel wire rope 910 receive uniform pressure, better transmit and disperse stress during fastening, and enhance the connection strength between the steel cable 90 and the fixed seat 20.

[0044] The number of the rope threading buckles 340 is set to four. Each rope threading buckle 340 is located between two adjacent partition rods 320 and includes two legs 341 movably assembled in the conical plug 310 along the radial direction of the conical plug 310, and a head 342 connected between two adjacent legs 341. The legs 341 of the rope threading buckle 340 are designed to allow radial movement within the conical plug 310, providing an adjustment space, so that the position can be automatically adjusted according to the diameter and force-bearing condition of the steel wire rope 910 during the fastening process. The head 342 is located in the extrusion space, and a through hole 343 for passing the steel wire rope 910 is formed on the side surface facing the outer side wall of the conical plug 310. The rope threading buckle 340 is used to guide each steel wire rope 910 in the steel cable 90 through the extrusion space, so as to ensure that the steel wire rope 910 can accurately enter the predetermined position during the installation process, avoiding fixing failure caused by the deviation or winding of the steel wire rope 910. In addition, the outer side surface of the head 342 of the rope threading buckle 340 can receive the extrusion force from the inner side wall of the conical chamber 210 and transmit it to the steel wire rope 910 in the through hole 343, thereby firmly fixing the steel wire rope 910 in the extrusion space and further improving the fixing reliability.

[0045] The bundling ring 350 is used to bundle the steel wire ropes 910 passing out of the conical chamber 210 through the passing-out end 212. The bundling ring 350 can cooperate with the part of the steel cable 90 that remains in a stranded state at the passing-in end 211, so that the steel wire ropes 910 at both axial ends of the conical plug 310 have a tendency to gather towards the central axis of the conical plug 310, which is beneficial to guiding the steel wire ropes 910 in the extrusion space to closely fit the outer side wall of the conical plug 310, thereby improving the fastening effect.

[0046] As Figure 2 and Figure 3 shown, the locking member 40 in the embodiment adopts an elastic force locking method and includes a locking ring 410 installed on the fixed seat 20 and located on the left side of the connecting ring 330, and a locking elastic member 420 connected between the locking ring 410 and the connecting ring 330. A plurality of locking elastic members 420 are circumferentially distributed between the connecting ring 330 and the locking ring 410 along the circumferential direction of the connecting ring 330. The locking elastic member 420 is a spring, and the locking elastic member 420 is used to apply an elastic force to the connecting ring 330 to move the fastener 30 to the right and push the conical plug 310 into the conical chamber 210, so that the conical plug 310 cooperates with the conical chamber 210 to tightly press and fix the steel wire rope 910. Elastic force locking can provide continuous pressure to prevent loosening, and it is fast and simple. In other embodiments, the locking member 40 can also adopt a locking method such as a hydraulic or pneumatic drive mechanism that can achieve the rightward movement of the fastener 30.

[0047] As Figure 2 and Figure 6As shown, the driving gear 50 is rotatably mounted on the fixed seat 20. The assembly column 510 is coaxially arranged with the driving gear 50, and an assembly groove 520 is formed on the assembly column 510. The assembly column 510 is used to dock with a wrench through the assembly groove 520, so that the staff can use the wrench to rotate the assembly column 510 to drive the driving gear 50 to rotate. A driven gear 411 that cooperates with the driving gear 50 and a clamping groove that is clamped and cooperated with the connecting ring 330 are provided on the locking ring 410. The connecting ring 330 is movably assembled on the locking ring 410 through the clamping block 331 with left and right guiding and circumferential limiting along the connecting ring 330, so as to rotate synchronously with the locking ring 410, thereby driving the fastener 30 to rotate. When the fastener 30 rotates, it can drive the steel wire rope 910 to rotate around the central axis of the tapered plug 310 through the rope threading buckle 340, so as to further untie the stranded part of the steel cable 90, which is convenient for subsequent tensioning adjustment.

[0048] As Figure 2 and Figure 7 shown, the fixing mechanism 60 is installed at the horizontal pipe section 220. The fixing mechanism 60 includes a plurality of arc-shaped locking pieces 610 distributed circumferentially along the horizontal pipe section 220 and a driver 620 corresponding to each arc-shaped locking piece 610 for driving each arc-shaped locking piece 610 to move radially along the horizontal pipe section 220. Each arc-shaped locking piece 610 is arc-shaped and has a pressing surface for fitting the outer surface of the steel cable 90. When the driver 620 drives the arc-shaped locking piece 610 to approach the steel cable 90 radially along the horizontal pipe section 220, the pressing surface of the arc-shaped locking piece 610 can abut against the outer surface of the steel cable 90. Each driver 620 includes a screw 621 rotatably connected to the arc-shaped locking piece 610 and a knob 622 provided at one end of the screw 621 away from the arc-shaped locking piece 610. The fixed seat 20 is provided with threaded holes corresponding to each screw 621 and threadedly connected to the screws 621 at the horizontal pipe section 220. In this way, the staff can rotate the knob 622, and the knob 622 drives the screw 621 to rotate, so that the arc-shaped locking piece 610 approaches or moves away from the steel cable 90 radially along the horizontal pipe section 220, thereby locking or unlocking the stranded state of the steel cable 90 at the fixing mechanism 60.

[0049] As Figure 2 、 Figure 6 and Figure 7As shown, the clamp 70 is arranged on the fixed seat 20 and is located on the left side of the fastener 30. The clamp 70 includes two relatively front and rear clamping bodies 710. The two clamping bodies 710 are respectively assembled to move left and right within the slider 231. The opposite side surfaces of the two clamping bodies 710 form a fixture groove 711 for receiving the steel wire rope 910. One end of the fixture groove 711 away from the fastener 30 extends outward to form a docking head 730. A converging spring 720 is provided between each slider 231 and the mounting frame 230. The converging spring 720 is used to apply an elastic force to the slider 231, so that the two sliders 231 approach each other, and drive the two clamping bodies 710 to approach each other, so as to close the two fixture grooves 711 to receive the steel wire rope 910. The docking head 730 is used to dock with the tensioning machine, so that the staff can use the tensioning machine to tension the steel cable 90.

[0050] The working process of the embodiment of the steel cable connection structure of the photovoltaic bracket of the present invention includes the following steps:

[0051] In the first step, for fixed installation, pull the fastener 30 to the left to reserve an installation space for the steel cable 90. The end of the steel cable 90 is inserted into the fixed seat 20 through the horizontal pipe section 220, and penetrates into the conical chamber 210 through the penetration end 211, and then is divided into multiple steel wire ropes 910, which pass through the extrusion space under the guidance of the rope threading buckle 340, and then pass through the conical chamber 210 through the penetration end 212. The separating rod 320 separates the steel wire ropes 910 independently. The steel wire rope 910 passing through the conical chamber 210 through the penetration end 212 passes through the converging ring 350 for converging, and then passes out through the fixture groove 711 of the clamp 70. Loosen the fastener 30, and the locking elastic member 420 applies an elastic force to the connecting ring 330, so that the fastener 30 moves to the right, and the conical plug 310 is pushed into the conical chamber 210, so that the conical plug 310 cooperates with the conical chamber 210 to press the steel wire rope 910 to complete the fixation.

[0052] Step 2: Tension adjustment. After fixation, due to factors such as the environment, construction errors, or installation deviations, the staff may need to tension the cable 90. First, the staff locks the stranding state of the cable 90 at the horizontal pipe section 220 through the fixing mechanism 60, then pulls the fastener 30 to the left to leave a loose space for the steel wire rope 910. Subsequently, use a wrench to rotate the assembly column 510 to drive the driving gear 50 to rotate. The driving gear 50 drives the locking ring 410 to rotate through the driven gear 411. The locking ring 410 drives the fastener 30 to rotate through the card slot. When the fastener 30 rotates, it drives the steel wire rope 910 to rotate around the central axis of the tapered plug 310 through the rope threading buckle 340, and further untangles the stranded part of the cable 90 between the fixing mechanism 60 and the tapered plug 310. After untangling, the staff can use a tensioning machine to connect to the joint 730, thereby pulling the cable 90 to make the untangled steel wire rope 910 enter the extrusion space to tension the cable 90. After the tensioning is completed, loosen the fastener 30 and fix the steel wire rope 910.

[0053] Thus, the beneficial effects of the embodiment of the cable connection structure of the photovoltaic bracket of the present invention are as follows:

[0054] 1. The fastener 30 and the locking member 40 are provided on the fixing seat 20. The end of the stranded cable 90 is dispersed to form multiple steel wire ropes 910, and the multiple steel wire ropes 910 enter the extrusion space formed between the tapered plug 310 and the tapered chamber 210. The steel wire ropes 910 are independently separated by the partition rod 320, and the tapered plug 310 is pushed into the tapered chamber 210 through the locking member 40, so that the tapered plug 310 cooperates with the tapered chamber 210 to tightly fix the steel wire rope 910. In this way, it can be ensured that each steel wire rope 910 exists independently in the extrusion space and is independently subjected to the extrusion force from the outer wall of the tapered plug 310 and the inner wall of the tapered chamber 210, thereby independently fixing each steel wire rope 910. Even if a certain steel wire rope 910 breaks or is damaged, it will not affect the fixing effect of other steel wire ropes 910, avoiding the overall fixing failure caused by the breakage of a single steel wire rope 910, and improving the reliability and safety of the entire cable 90 connection mechanism. In addition, fixing each steel wire rope 910 independently can also make each steel wire rope 910 receive uniform pressure, better transmit and disperse stress during fastening, and enhance the connection strength between the cable 90 and the fixing seat 20.

[0055] Second, a driving gear 50, a fixing mechanism 60 and a clamp 70 are arranged on the fixed seat 20. The fixing mechanism 60 locks the stranding state of the cable 90 at the horizontal pipe section 220.
