Description

Technical Field

[0001] The utility model belongs to the technical field of wire harnesses, in particular to a heliostat wire harness. Background Art

[0002] Tower-type solar thermal power generation (CSP) is an energy conversion technology that effectively utilizes solar energy for power generation. The solar thermal collection system consists of a field of concentrating heliostats and a heat receiver located on a central tower. The light spot from each heliostat in the field is focused onto the heat receiver located on a high tower in the center of the field, where it is circulated and heated. The heated working fluid is then stored in a high-temperature tank. A heat pump then drives the hot working fluid through a heat exchanger to exchange heat with water and steam, generating superheated steam that drives a steam turbine to drive a generator for power generation.

[0003] Heliostats are the core equipment of a concentrated solar thermal power plant. Due to their large number, the design of a CSP plant requires consideration of multiple factors, including the installation and maintenance of the heliostat wiring system, as well as cost management during construction and operation.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0035] The utility model discloses a composite wiring harness, which can be applied in multiple fields such as solar energy and automobiles. The utility model takes a heliostat wiring harness in the solar energy field as a specific embodiment to further illustrate the utility model in detail.

[0036] The heliostat wiring harness includes the heliostat upper wiring harness and the heliostat buried wiring harness, and the heliostat upper wiring harness includes the heliostat upper down conductor harness, the heliostat electric push rod harness, etc.

[0037] like Figures 1 to 3 As shown, an embodiment of the present invention discloses a buried wiring harness for heliostats, which is used for power supply and communication between heliostats. The buried wiring harness for heliostats includes a first composite cable 1 and a connector assembly. At least two connector assemblies are provided. This structure is also applicable to multi-pass wiring harnesses, where a composite cable has multiple wiring harness ends, each connected to a connector assembly. The buried wiring harness for heliostats disclosed in this embodiment utilizes a first composite cable with a set of connector assemblies at each end.

[0038] The first composite cable 1 is used for power supply and communication. A heliostat site is designed to contain tens of thousands of heliostats, and communication control is employed. To save investment costs, a single cable is often used for both power and communication. This combined power and communication cable is commonly referred to as the "first composite cable." Communication control and power transmission are performed via the first composite cable 1.

[0039] In one specific embodiment, the first composite cable 1 can be an armored composite cable, which is composed of a power line and a communication line, and is used to connect power and communication between heliostats. The buried heliostat wiring harness disclosed in this embodiment is typically a wiring harness buried below the heliostat. The armored composite cable is provided with a mechanical protective layer on the outside, which protects the cable while increasing the mechanical strength of the first composite cable 1, improving its corrosion resistance, and enhancing the tensile strength and compressive strength of the cable, thereby extending its service life. The armored composite cable can be used for underground installation, extending its service life while reducing costs and increasing efficiency.

[0040] Furthermore, the connector assembly includes a first connector body 2 and a second connector body 5. One end of the first connector body 2 is electrically connected to the first composite cable 1, the other end of the first connector body 2 is plugged into the second connector body 5, and the end of the second connector body 5 facing away from the first connector body 2 is electrically connected to the device to be connected. When the first connector body 2 and the second connector body 5 are in the plugged state, the first connector body 2 and the second connector body 5 are internally electrically connected.

[0041] Compared with the prior art, this embodiment has the following advantages and technical effects:

[0042] (1) The utility model eliminates the need for on-site construction personnel to perform wiring by plugging the first connector body and the second connector body in the connector assembly, thereby improving construction efficiency.

[0043] (2) When the first connector body and the second connector body are plugged in, electrical conduction is achieved between the inside of the first connector body and the second connector body, reducing the error rate and unreliable connection caused by traditional wiring.

[0044] (3) If a fault occurs during use, it can be disconnected from the connector assembly, which facilitates the replacement of control equipment and troubleshooting, reducing maintenance costs during the operation period.

[0045] (4) The on-site construction of the heliostat control box of the utility model saves manpower, improves installation efficiency, and shortens construction period.

[0046] In this embodiment, various methods such as plug terminals and docking plugs can be used to connect the first connector body 2 and the second connector body 5. In this embodiment, a stepped hole is provided in the interior of the second connector body 5 along its axial direction. When the first connector body 2 and the second connector body 5 are in the plugged state, the shoulder of the stepped hole contacts the first connector body 2, and the stepped hole needs to be compatible with the plug-in end of the first connector body 2.

[0047] During implementation, the end of the first connector body 2 close to the second connector body 5 is inserted into the stepped hole. When one end of the first connector body 2 contacts the shoulder of the stepped hole, the insertion is stopped, and the axial positioning of the first connector body 2 is achieved through the shoulder of the stepped hole. The construction operation is carried out in this simple but fast plug-in method, which greatly improves work efficiency.

[0048] A further optimized solution is that an elastic ear 8 is provided on the outer side of the first connector body 2, and one end of the elastic ear 8 is fixedly connected to the side of the first connector body 2 close to the second connector body 5; a tongue 9 is provided on the side of the elastic ear 8 facing away from the first connector body 2, and the second connector body 5 is provided with a tongue groove 10 on the inner wall of the stepped hole. When the first connector body 2 and the second connector body 5 are in the plugged-in state, the tongue 9 and the tongue groove 10 are engaged, and the non-fixed end of the elastic ear 8 is on the outside of the stepped hole.

[0049] In this optimized solution, two sets of elastic latches 8 are provided, employing a double-snap structure. The two sets of elastic latches 8 are respectively provided on either side of the first connector body 2. During operation, the first connector body 2 is inserted into the stepped hole. When the shoulder of the stepped hole contacts the first connector body 2, the latching tongue 9 on the elastic latch 8 snaps into the latching tongue groove 10, enhancing the anti-slip force and achieving a secure locking effect.

[0050] When the first connector body 2 and the second connector body 5 need to be separated, when the non-fixed end of the elastic ear 8 is more outside the stepped hole, the elastic ear 8 can be directly pressed manually to make the tongue 9 pop out from the tongue groove 10, and then the first connector body 2 can be pulled out from the stepped hole; when the non-fixed end of the elastic ear 8 is less outside the stepped hole, the elastic ear 8 can be pressed from the gap between the first connector body 2 and the second connector body 5 by using a tool such as a screwdriver to make the tongue 9 pop out from the tongue groove 10, and then the first connector body 2 can be pulled out from the stepped hole. In this way, the first connector body 2 and the second connector body 5 can be disengaged, thereby preventing arbitrary disassembly by humans.

[0051] In one embodiment, the first connector body 2 is fixedly connected to the first composite cable 1. The first connector body 2 is connected to a first fastening portion, which is sleeved on the outside of the first composite cable 1. The first fastening portion is used to fix the position of the first composite cable 1 relative to the first connector body 2, preventing the first composite cable 1 from loosening or rotating relative to the first connector body 2, thereby avoiding the firmness of the connection between the first connector body 2 and the first composite cable 1 caused by loosening or rotation, and improving the stability and reliability of the composite wiring harness.

[0052] Preferably, the first fastening portion can be implemented using fasteners such as an annular fastener, a C-shaped wire clamp, or an elastic clamp. In this embodiment, the first fastening portion is implemented using a first wire harness locking tail clip 3. One end of the first wire harness locking tail clip is sleeved onto the end of the first connector body 2, and the other end of the first wire harness locking tail clip 3 is sleeved onto the outside of the first composite cable 1. Specifically, the first wire harness locking tail clip 3 is sleeved onto the connection between the first connector body 2 and the first composite cable 1. By applying a compressive force to the first wire harness locking tail clip 3, the first wire harness locking tail clip 3 securely clamps the first connector body 2 and the first composite cable 1, thereby preventing the first composite cable 1 from loosening or rotating relative to the first connector body 2.

[0053] In a further optimized solution, a male connector pin 4 is fixedly disposed inside the first connector body 2, and the male connector pin 4 is fixed to and electrically connected to the first composite cable 1; a female connector jack 7 is fixedly connected to the second connector body 5, and the male connector pin 4 is plugged into and electrically connected to the female connector jack 7, and the other end of the female connector jack 7 is electrically connected to the device to be connected. A colloid layer is disposed within the cavity formed by the first connector body 2 and the first fastening portion. This embodiment uses the electrical conduction method of the male connector pin 4 and the female connector jack 7 to achieve electrical conduction between the first connector body 2 and the second connector body 5. Alternatively, a structure such as a terminal block can be used to achieve electrical conduction between the first connector body 2 and the second connector body 5.

[0054] The plug-in structure of the male connector pin 4 and the female connector jack 7 achieves both power supply and communication functions, improving the stability of the connection structure, thereby enhancing communication stability and the reliability of the communication link connection. This solves the technical problem of relatively poor connection reliability using conventional wiring methods in the prior art, resulting in unstable communication and thus affecting the stability of control and tracking of the entire heliostat. Furthermore, this plug-in structure can further improve the stability and accuracy of the plug-in connection between the first connector body 2 and the second connector body 5.

[0055] Furthermore, the connector male pin 4 and the first composite cable 1 are welded together to achieve both a structurally fixed connection and an electrical connection for communication purposes. This welding method further enhances communication stability. During installation, the connector male pin 4 is first welded to the first composite cable 1, and then fixedly connected to the first connector body 2. After connection, glue is poured into the cavity of the first connector body 2 to form a gel layer. This gel layer not only strengthens the weld strength between the inner conductor of the first composite cable 1 and the connector male pin 4, but also prevents oxidation of the weld during long-term use. After the glue is poured, the first harness locking tail clip 3 securely clamps the first connector body 2 and the first composite cable 1, further preventing the first composite cable 1 from loosening or rotating and improving reliability.

[0056] In one embodiment, a first sealing portion is provided in the second connector body 5. When the first connector body 2 and the second connector body 5 are in the plugged state, the first sealing portion is in contact with the first connector body 2. The first sealing portion provides a seal between the first connector body 2 and the second connector body 5, thereby achieving a waterproof and dustproof sealing effect.

[0057] Preferably, a first O-ring 11 is embedded in the shaft shoulder of the second connector body 5. When the first connector body 2 and the second connector body 5 are in the plugged state, the first O-ring 11 is tightly fitted with the second connector body 5 and the end surface of the first connector body 2. This forms a sealed space within the internal cavities of the first connector body 2 and the second connector body 5, achieving a dustproof and waterproof sealing effect. The first sealing ring in this embodiment can also be a V-shaped sealing ring, a U-shaped sealing ring, or the like for sealing.

[0058] In one embodiment, an annular protrusion is fixedly provided on the outer side of the second connector body 5, and a plurality of through holes are opened on the circumference of the annular protrusion, and screw assemblies 6 are detachably connected to the through holes. During installation, the wire inside the device to be connected is connected to the female connector jack 7 inside the second connector body 5. After that, the first connector body 5 is placed in the box of the device to be connected, and the end of the second connector body 5 close to the first connector body 2 is passed through the box, and the annular protrusion on the second connector body 5 is tightly fitted with the inner wall of the box. The box and the second connector body 5 are then fixedly connected by the screw assembly 6, and the first connector body 2 is then inserted into the second connector body 5. The structure after installation is as shown below. Figure 2 This embodiment adopts the installation from the inside out of the box and is fixed with multiple sets of screw assemblies 6. This can strengthen the fixed connection strength between the second connector body 5 and the box, enabling outdoor use, effectively improving the reliability of the equipment and extending its service life.

[0059] This embodiment further discloses a heliostat harness, which includes an upper heliostat harness and a heliostat buried harness. The upper heliostat harness further includes an upper downconductor harness, a heliostat electric push rod harness, and the like.

[0060] The heliostat wiring harness includes the composite wiring harness disclosed in the above embodiment and at least one second wiring harness; the composite wiring harness is the buried wiring harness of the heliostat. The second wiring harness includes a second composite cable 12, a Gland plug 18, and / or a connector wiring harness assembly. The second composite cable 12 is composed of a power line and a communication line, and is used for power supply and / or communication, thereby reducing costs and increasing efficiency. The Gland plug 18 and / or the connector wiring harness assembly are connected to the end of the second composite cable 12. The end of the second composite cable 12 passes through the Gland plug 18 and is fixedly connected to a plastic shell and terminal assembly 20, which is electrically connected to the device to be connected. One end of the connector wiring harness assembly is electrically connected to the second composite cable 12, and the other end of the connector wiring harness assembly is electrically connected to the device to be connected, thereby achieving conductivity of power supply and communication from the device to the cable and then to the device.

[0061] The end of the second composite cable 12 passes through a gland 18 and is then fixedly connected to a plastic housing and terminal assembly 20. First, the second composite cable 12 is locked by the gland 18, and the connecting device and the second composite cable 12 are secured via the gland 18 and a matching nut. Second, the conductors 19 within the second composite cable 12 are press-fitted into the plastic housing and terminal assembly 20. The conductors 19 extending beyond the gland are both located within the device, and the plastic housing and terminal assembly 20 are compatible with the internal interface of the device, allowing for quick connection. This eliminates the need for on-site cable stripping and wiring, improving installation efficiency and accuracy.

[0062] In addition, the connector harness assembly includes a third connector body 13, which is connected to a second fastening portion. The second fastening portion is sleeved on the outside of the second composite cable 12. The second fastening portion is used to fix the position of the second composite cable 12 relative to the third connector body 13, preventing the second composite cable 12 from loosening or rotating relative to the third connector body 13, thereby avoiding the firmness of the connection between the third connector body 13 and the second composite cable 12 caused by loosening or rotation, thereby improving the stability and reliability of the composite harness.

[0063] Preferably, the second fastening portion can be implemented using fasteners such as an annular fastener, a C-shaped wire clamp, or an elastic clamp. In this embodiment, the second fastening portion is implemented using a second wire harness locking tail clip 14. One end of the second wire harness locking tail clip 14 is sleeved onto the end of the third connector body 13, and the other end of the second wire harness locking tail clip 14 is sleeved onto the outside of the second composite cable 12. In other words, the second wire harness locking tail clip 14 is sleeved onto the connection between the third connector body 13 and the second composite cable 12. By applying a compressive force to the first wire harness locking tail clip 3, the second wire harness locking tail clip 14 securely clamps the second composite cable 12 and the third connector body 13, thereby preventing the second composite cable 12 from loosening or rotating relative to the third connector body 13.

[0064] A further optimization scheme features a connector pin 15 installed within the third connector body 13. This pin is secured and electrically connected to the second composite cable 12. A colloid layer is incorporated into the cavity formed by the third connector body 13 and the second fastening portion. Furthermore, a wire connection structure compatible with the connector pin 15 is provided within the connected device, enabling a quick connection between the two devices. This improves operational efficiency while also enhancing communication stability and link reliability. Furthermore, the connector pin 15 and the second composite cable 12 are welded together to achieve both structural and electrical connection, further enhancing communication stability.

[0065] During installation, the connector pin 15 is first welded to the second composite cable 12. The connector pin 15 is then fixedly connected to the third connector body 13. After connection, glue is poured into the cavity of the third connector body 13 to form a gel layer. This gel layer not only strengthens the weld between the inner conductor of the second composite cable 12 and the connector pin 15, but also prevents oxidation at the weld during long-term use. After the glue is poured, the second composite cable 12 and the third connector body 13 are securely clamped together using the second harness locking tail clip 14, further preventing the second composite cable 12 from loosening or rotating, thereby improving reliability.

[0066] In one embodiment, the side of the third connector body 13 closest to the device to be connected is sequentially provided with a retaining protrusion, a second O-ring 17, and a connector harness assembly lock nut 16. The retaining protrusion is fixedly connected to the third connector body 13. During installation, the second O-ring 17 and connector harness assembly lock nut 16 are first removed. Then, the side of the third connector body 13 closest to the device to be connected is inserted into the device housing, with the retaining protrusion positioned outside the housing. The second O-ring 17 and connector harness assembly lock nut 16 are then sequentially installed onto the third connector body 13 within the housing. Finally, the connector pin 15 is connected to the lead wire assembly within the device housing, establishing an electrical connection between the second composite cable 12 and the connector harness assembly and the device within the control box for power supply and communication. In this embodiment, the retaining protrusion and connector harness assembly lock nut 16 strengthen the fixed connection strength between the third connector body 13 and the housing. Simultaneously, the second O-ring 17 forms a sealed space between the third connector body 13 and the housing, achieving a dust-proof and waterproof seal.

[0067] The second harness includes various forms:

[0068] like Figure 4 The second wiring harness shown includes a second composite cable 12 and a Gland plug 18 and a connector harness assembly provided at both ends of the second composite cable. This wiring harness is a down-lead harness for the upper portion of the heliostat, used to connect power and communication to the upper drive and control equipment of the heliostat. One end of the Gland plug of the down-lead harness is connected to the upper drive and control equipment of the heliostat, and one end of the connector harness assembly of the down-lead harness is connected to the lower control box of the heliostat or its supporting components.

[0069] like Figure 5 The second wiring harness shown includes a second composite cable 12 and a set of Gland heads arranged at both ends of the second composite cable. The wiring harness is a heliostat electric push rod wiring harness. One end of the heliostat electric push rod wiring harness is connected to the upper drive device of the heliostat, and the other end is connected to the heliostat control device.

[0070] The utility model discloses a wiring harness and designs and arranges a whole set of heliostat integrated wiring harnesses, thereby realizing the integration of heliostat installation and integrated wiring, which is neat and beautiful.
