[0002] The dual-axis trough solar collector rotates around the solar azimuth through a slewing reducer and rotates around the solar altitude through an electric push rod to achieve dual-axis tracking around the sun. Since the slewing reducer is equipped with wires, the reserved length of the wires is limited and it cannot rotate 360° infinitely. In addition, the azimuth rotation requires a signal to the software program to determine whether the collector rotates around the solar azimuth, so the azimuth rotation requires a limit mechanism. The limit mechanism restricts the collector from rotating 360° and also serves to transmit signals. Always keep parallel sunlight vertically reflected on the reflector.

[0003] The existing limit mechanism is mainly composed of a limit rod and a travel switch, which plays a limiting role under the cooperation of the limit rod and the travel switch, and can prevent the slewing reducer from rotating 360 degrees. Since the travel switch is easily damaged after long-term use, it needs to be replaced, but the existing travel switch is troublesome to replace, which affects the replacement efficiency.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0021] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0023] refer to Figure 1-5, now an azimuth limiting mechanism of a dual-axis trough type solar collector provided by an embodiment of the utility model is described. An azimuth limiting mechanism of a dual-axis trough type solar collector comprises a column 1, a positioning tube 2 is fixedly connected to the upper end of the column 1, a rotating frame 3 is rotatably connected to the upper end of the positioning tube 2, a rotary reducer 4 is fixedly connected to the lower end of the rotating frame 3, a connecting frame 5 is fixedly connected to the upper end of the rotating frame 3, and a limiting rod 6 is fixedly connected to the lower end of the connecting frame 5; a mounting frame 7 is fixedly connected to the upper end of the positioning tube 2, a connecting assembly 9 and a travel switch 10 are arranged inside and at the lower end of the mounting frame 7, the mounting frame 7 is connected to the travel switch 10 through the connecting assembly 9, and a positioning assembly 8 is arranged inside the mounting frame 7; two mounting frames 7 are arranged, and are symmetrically distributed on both sides of the connecting frame 5, one mounting frame 7 is a starting mounting frame 7, and the other mounting frame 7 is a terminating mounting frame 7.

[0024] Specifically, when the rotary reducer 4 is working, it drives the rotating frame 3 to rotate, and drives the limit rod 6 to rotate with the cooperation of the connecting frame 5. When the limit rod 6 contacts the travel switch 10 on the starting mounting frame 7, the rotary reducer 4 is closed and reset; when the limit rod 6 contacts the travel switch 10 on the ending mounting frame 7, the rotary reducer 4 reaches a position to stop its rotation, which can prevent it from rotating 360 degrees; when the travel switch 10 needs to be replaced, the positioning component 8 is used to release the limitation of the connecting component 9, so that the travel switch 10 can be removed from the mounting frame 7 for replacement, which is convenient for disassembly and installation of the travel switch 10, thereby improving work efficiency.

[0025] The connection assembly 9 includes a socket 901 and a plug block 902. The socket 901 is fixedly connected to the inside and the lower end of the mounting frame 7. The plug block 902 is plugged into the socket 901. The lower end of the plug block 902 is fixedly connected to the travel switch 10. When working, the plug block 902 of the travel switch 10 is inserted into the socket 901 to complete the preliminary installation, so that the positioning assembly 8 can limit the travel switch 10 later.

[0026] The positioning assembly 8 includes a positioning rod 801, a guide rod 802 and a guide seat 803. The guide rod 802 is fixedly connected inside the mounting frame 7. The guide seat 803 is slidably connected to the circumferential surface of the guide rod 802. The end of the guide seat 803 close to the plug-in seat 901 is fixedly connected to the positioning rod 801. The positioning rod 801 is slidably connected to the mounting frame 7. The upper end surface of the plug-in block 902 is provided with a positioning groove 13, and the positioning groove 13 cooperates with the positioning rod 801. During operation, when the plug-in block 902 is inserted into the plug-in seat 901 and the plug-in block 902 contacts the positioning rod 801, the positioning rod 801 will be squeezed to move upward, thereby driving the guide seat 803 to slide on the guide rod 802. When the positioning rod 801 reaches the positioning groove 13, the positioning rod 801 is reset and can be inserted into the positioning groove 13, so that the plug-in block 902 is limited under the cooperation of the positioning rod 801 and the positioning groove 13, thereby preventing the travel switch 10 from being separated from the mounting frame 7.

[0027] The side end of the upper end of the positioning rod 801 is fixedly connected with an auxiliary plate 11. During operation, under the action of the auxiliary plate 11, the positioning rod 801 is conveniently pulled upward, thereby releasing the restriction on the plug-in block 902, and facilitating the replacement of a new travel switch 10.

[0028] The circumferential surface of the guide rod 802 is provided with a spring 12, one end of the spring 12 is fixedly connected to the guide seat 803, and the other end of the spring 12 is fixedly connected to the mounting bracket 7. During operation, the spring 12 facilitates the positioning rod 801 to reset.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
