Abstract
Description
Technical Field
[0001] This utility model belongs to the field of trough solar collector applications, and specifically relates to an assembly tool for the forward installation of trough solar collectors. Background Technology
[0002] Parabolic trough solar thermal power generation systems utilize focusing solar collectors to convert solar radiation energy into heat energy. Among the key aspects of parabolic trough solar thermal power plant construction, collector assembly is crucial, as its assembly precision directly affects the focusing effect of the reflectors and the photothermal conversion efficiency. Within the parabolic trough collector assembly process, the final assembly of the collectors is particularly important, as it directly determines the assembly precision of the collectors.
[0003] While the assembly fixtures for standard parabolic trough solar collectors are becoming increasingly sophisticated, they all currently employ an inverted installation method. This method requires manual positioning during installation, followed by the use of specialized large-scale tilting equipment to flip the collector back to its upright position. This process is labor-intensive. Furthermore, the collector remains in a flexibly suspended state throughout the tilting process, resulting in significant swaying and a high risk of detachment. In addition, the installation workshop demands substantial space for the collectors. As parabolic trough solar thermal power generation systems develop, collectors are becoming increasingly larger, exacerbating these problems. Therefore, there is an urgent need to develop a fixture that enables upright installation to meet the growing trend of larger collectors. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an assembly fixture for the forward installation of a trough-type solar collector, which can realize automated positioning and forward installation of the solar collector. It not only solves the problem of inverted installation of the solar collector and avoids the risks in the process of flipping the solar collector from inverted to forward, but also saves labor costs and installation procedures, greatly reduces installation costs, improves production efficiency, and improves the assembly stability of the solar collector.
[0005] The main technical solution adopted in this utility model is as follows:
[0006] An assembly fixture for the forward installation of a trough-type solar collector includes two sets of crossbeams, a main fixture mechanism, at least two sets of reflector support and positioning truss mechanisms, and a solar collector body positioning mechanism.
[0007] The main tooling structure includes several supporting columns for connecting to the ground and supporting the crossbeams;
[0008] The two sets of crossbeams are parallel to each other and are arranged along the length of the collector, and are used to install the reflector support and positioning truss mechanism;
[0009] At least two sets of reflector support positioning truss mechanisms are fixedly or slidably installed on the crossbeam and cover the length direction of the solar collector for positive positioning and installation of the reflectors;
[0010] The solar collector body positioning mechanism is installed on the ground and is used to support and position the solar collector in a positive direction.
[0011] Preferably, a transmission rack and a sliding guide rail are provided on the crossbeam along the length of the crossbeam, and the transmission rack and the sliding guide rail are parallel to each other. The transmission rack is connected to the reflector support and positioning truss mechanism for transmission. The reflector support and positioning truss mechanism is slidably mounted on the sliding guide rail and moves along the sliding guide rail.
[0012] Preferably, the reflector support and positioning truss mechanism includes a truss body, a plurality of reflector support and positioning components, and a heat collector tube support and positioning component, wherein,
[0013] The two ends of the truss body are respectively fixed or slidably installed on the crossbeam;
[0014] Several of the aforementioned mirror support and positioning components are installed below the truss body. The aforementioned mirror support and positioning components are arranged symmetrically in pairs along the length direction of the truss body, and at the same time, the mirror support and positioning components are arranged symmetrically in pairs along the width direction of the truss body, for positioning and installing the mirrors.
[0015] Preferably, both ends of the truss body are slidably connected to the sliding guide rail on the crossbeam via sliders. A servo reduction motor is installed on the truss body near the inner side of the slider. A gear is installed on the drive end of the servo reduction motor. The gear meshes with the transmission rack and is used to drive the truss body to move along the sliding guide rail.
[0016] Preferably, the reflector support and positioning assembly includes a forward positioning component, a movable gripping component, and a clamping component, wherein the forward positioning component positions the reflector connector at the connection position; the movable gripping component grips the reflector connector and fixes it in the required installation position; and the clamping component clamps the reflector connector so that the assembly surfaces of each reflector connector fit tightly together.
[0017] Preferably, the forward positioning component is a forward fixed positioning component or a forward movable positioning component. When the forward positioning component is a forward fixed positioning component, the solar collector is moved to disengage from the reflector support positioning assembly. When the forward positioning component is a forward movable positioning component, the forward movable positioning component drives the moving gripper and clamping component to move, thereby disengaging the reflector support positioning assembly from the solar collector.
[0018] Preferably, the solar collector body positioning mechanism includes a shaft end positioning component, which engages with the rotation center shaft of the solar collector through an arc groove to position the central axis and height of the solar collector.
[0019] Beneficial effects: This utility model provides an assembly fixture for the forward installation of a trough-type solar collector, which has the following advantages:
[0020] (1) The present invention adopts a forward reflector support and positioning structure to realize the forward installation of the trough collector. This not only eliminates the overall flipping process of the collector assembly, avoiding the safety risks that exist during the flipping process, but also solves and reduces the equipment investment in the assembly process, improves the assembly efficiency, reduces the actual height of the assembly workshop, and fundamentally reduces the cost of the assembly process. Moreover, it reduces the forward use and reverse installation process in the middle process, avoiding the problem of inconsistent use and assembly directions, thereby solving the error problem caused by the deflection deformation of the collector due to its own gravity, and improving the overall surface accuracy of the collector.
[0021] (2) The present invention adopts an automatic positioning and gripping structure design, which avoids the problem of unstable positioning caused by manual positioning and greatly improves the product consistency and stability of the solar collector. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application. Example
[0030] An assembly tooling for forward installation of a parabolic trough collector, such as Figure 1-2 As shown, it includes two sets of crossbeams 1, a main tooling mechanism, at least two sets of reflector support and positioning truss mechanisms 2, and a collector body positioning mechanism 3, wherein,
[0031] The main structure of the tooling includes several supporting columns 4, which are used to connect to the ground and support the crossbeams 1;
[0032] Two sets of crossbeams 1 are parallel to each other and are arranged along the length of the collector to install the reflector support and positioning truss mechanism 2;
[0033] At least two sets of reflector support positioning truss mechanisms 2 are fixedly or slidably installed on the crossbeam 1 and cover the length direction of the solar collector for positive positioning and installation of the reflectors;
[0034] The collector body positioning mechanism 3 is installed on the ground to support and position the collector in a positive direction.
[0035] In this embodiment 1, a transmission rack 1-1 and a sliding guide rail 1-2 are provided on the crossbeam 1 along the length of the crossbeam, and the transmission rack 1-1 and the sliding guide rail 1-2 are parallel to each other. The transmission rack 1-1 is connected to the reflector support and positioning truss mechanism 2 for transmission. The reflector support and positioning truss mechanism 2 is slidably installed on the sliding guide rail 1-2 and moves along the sliding guide rail 1-2.
[0036] In this embodiment 1, the reflector support and positioning truss mechanism 2 includes a truss body 2-1 and a plurality of reflector support and positioning components 2-2, wherein...
[0037] The two ends of the truss body 2-1 are slidably mounted on the crossbeam 1. The specific sliding mounting structure is as follows: the two ends of the truss body 2-1 are slidably connected to the sliding guide rail 1-2 on the crossbeam 1 through the slider 2-11. A servo reduction motor 2-12 is installed on the truss body 2-1 near the inner side of the slider. A gear 2-13 is installed on the drive end of the servo reduction motor 2-12. The gear 2-13 meshes with the transmission rack 1-1 and is used to drive the truss body 2-1 to move along the sliding guide rail 1-2.
[0038] like Figure 3-4 As shown, several reflector support and positioning components 2-2 are installed below the truss body 2-1. These components are symmetrically arranged in pairs along the length and width of the truss body 2-1, and are used to position and install the reflectors. In this invention, the reflector support and positioning components 2-2 can be arranged according to the installation angle and position of the reflectors in the solar collector, as well as the parabolic surface type of the reflectors. In this embodiment 1, the reflector support and positioning assembly 2-2 includes a forward positioning component, a moving gripper 2-22, and a clamping component 2-23. The forward positioning component is a forward moving positioning component 2-21, which is used to position the connection position and angle of the reflector connector. The moving gripper 2-22 grips the reflector connector, fixing it in the installation position. The clamping component clamps the reflector connector, ensuring a tight fit between the assembly surfaces of each reflector connector, preventing positional movement when fastened with fasteners. In this invention, the forward moving positioning component, moving gripper, and clamping component can all be driven by cylinders, which is a conventional technique and therefore not described in detail. In this invention, there are two main types of reflector connectors: one is a ceramic plate assembled with the reflector, with a pre-embedded nut inside; the other is a purlin on the collector. The reflector is connected to the purlin via the nut on the ceramic plate and screws. Figure 5 As shown, the forward moving positioning component 2-21 moves up and down. When it moves to the lower position, it is the positioning position of the reflector connector (purlin). The moving gripping component 2-22 moves left and right. When it moves to the right position, it can grip the reflector connector (purlin). The clamping component 2-23 moves upward to clamp the reflector connector (purlin).
[0039] In this embodiment 1, as Figure 6 As shown, the solar collector body positioning mechanism 3 includes a shaft end positioning component 3-1. The shaft end positioning component 3-1 is fitted with the rotating central shaft of the solar collector through an arc groove 3-2, that is, the rotating central shaft of the solar collector is placed in the arc groove 3-2, which is used to position the position and height of the rotating central axis of the solar collector.
[0040] In this invention, two or more sets of reflector support and positioning truss mechanisms 2 can be provided, and each set of reflector support and positioning truss mechanisms 2 has the same structure. Moreover, each set of reflector support and positioning truss mechanisms 2 can operate and be positioned independently, or they can cooperate with each other, thereby realizing the positive positioning and installation function of the reflector support of the solar collector.
[0041] In this utility model, the two ends of the truss body 2-1 can also be fixedly installed on the crossbeam or can be installed in conjunction with the crossbeam using a guide railless gear rack drive method. Existing installation methods that can realize the arrangement and installation of the truss body 2-1 on the crossbeam can all arrange multiple sets of positive reflector support and positioning truss mechanisms 2 to cover the entire length direction of the solar collector, thereby realizing the positive positioning and installation function of the solar collector reflector support.
[0042] Taking Example 1 as an example, the working principle of the forward assembly of this utility model will be explained:
[0043] First, adjust the position of the reflector support and positioning truss mechanism 2 according to the different angles and positions of the reflectors installed on the solar collector. Control the servo reduction motor 2-12 to drive the gear 2-12 to rotate, and through meshing transmission, drive the reflector support and positioning truss mechanism 2 to move on the crossbeam 1 to the installation position. At this time, the forward moving positioning component 2-21, the moving gripping component 2-22, and the clamping component 2-23 in the reflector support and positioning assembly 2-2 installed on the truss mechanism 2 are all in the retracted stop position (i.e., the initial position).
[0044] When it is necessary to position and install the supporting components connected to the reflector (such as purlins, reflector ceramic gasket connectors, etc.), control the forward moving positioning component 2-21 to move to the required positioning position (e.g., the purlin position where the reflector ceramic gasket is located), and the moving gripper 2-22 grips each reflector connector, fixing each reflector connector in the required installation position; the clamping component 2-23 clamps each reflector connector, ensuring that the mating surfaces of each reflector connector fit tightly, ensuring that the reflector connectors will not move when fastened with fasteners. After the operator has tightened each reflector connector, control the forward moving positioning component 2-21, the moving gripper 2-22, and the clamping component 2-23 to perform the reverse operation, releasing the clamping component 2-23 and the moving gripper 2-22 in sequence, and then control the forward moving positioning component 2-21 to retract to the retracted stop position (i.e., the initial position), so that the reflector support positioning assembly 2-2 is disengaged from the collector, completing the installation operation. Example
[0045] Compared to Example 1, the forward positioning component in Example 2 is a forward fixed positioning component. The collector can be moved to detach it from the reflector support positioning assembly 2-2. The remaining structure and installation method are the same as in Example 1, and the method for achieving forward assembly of the collector is also the same as in Example 1. Moving the collector is a conventional technique, and existing methods for moving collectors are applicable; therefore, they are not described in detail.
[0046] The forward assembly and installation method of this utility model can be applied to the forward installation of various types of parabolic trough solar collectors. The number, angle and position of the reflector support and positioning components can be adaptively adjusted as needed to adapt to the forward assembly of parabolic trough collectors of different types.
[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
