Description

Technical Field

[0001] This utility model relates to the field of drone cleaning equipment technology, and in particular to a tow pipe positioning device. Background Technology

[0002] There are two cleaning modes in drone cleaning: water tank cleaning and tethered cleaning. Tethered cleaning relies on a real-time water supply through a water pipe to ensure the continuity of drone cleaning. Therefore, water supply through a water pipe is the key to improving the cleaning effect in drone tethered cleaning. However, due to terrain, operating environment and other reasons, the length of the water pipe can be hundreds of meters and the total weight can be hundreds of kilograms. At the same time, the support structure of the photovoltaic area is relatively complex, with various protrusions and obstructions. The complex path can easily cause the water supply pipe to be blocked or entangled with the photovoltaic support, which seriously affects the towing of the water pipe.

[0003] In summary, developing a device that is easy to install and can limit the dragging route of water supply pipes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a tow pipe positioning device, which solves the technical problem that when a drone connects to a water supply pipe to clean a photovoltaic support, the water supply pipe is blocked or bent and jammed by obstacles during the drone's towing process due to the complex structure of the photovoltaic support.

[0005] To achieve the above objectives, this utility model provides a tow pipe positioning device for elastically clamping a water supply pipe onto a photovoltaic support, comprising:

[0008] The second roller is fixed to the first fixed crossbar by two parallel mounting rods and is spaced apart from the first roller. The mounting rods are located between the guide rods and are arranged along the length of the guide rods.

[0009] A fixed bracket is rotatably connected to the second fixed crossbar;

[0010] The first roller, under the action of the first elastic element, forms an elastic clamping space with the second roller.

The edge of the first fixed crossbar is provided with a relief groove, which is connected to the mounting hole through which the second guide rod passes. The first fixed crossbar is rotated with the first guide rod as the pivot, so that the second guide rod is disengaged from the relief groove, so as to place the water supply pipe on the first roller.

[0013] Preferably, a connecting rod is vertically inserted through the second fixed crossbar, and a third fixed crossbar is rotatably connected to the end of the connecting rod away from the first fixed crossbar. The third fixed crossbar is arranged parallel to the first fixed crossbar.

[0014] Preferably, positioning screws are vertically inserted through both ends of the third fixed crossbar along its length. The positioning screws extend into the fixed bracket and into the groove inside the photovoltaic bracket. The positioning screws hold the photovoltaic bracket in place, so that the photovoltaic bracket and the fixed bracket fit tightly together.

[0015] Preferably, a second elastic element is sleeved on the outer periphery of the positioning screw, and the two ends of the second elastic element abut against the third fixed crossbar and the fixed bracket, respectively.

[0016] Preferably, the third fixed crossbar is provided with a connecting hole, and a limiting sleeve is fitted on the end of the positioning screw that passes through the connecting hole, and the limiting sleeve abuts against the third fixed crossbar.

[0017] Preferably, the diameter of the second roller gradually decreases towards the midpoint of its axis, making the sidewall of the second roller an arc surface.

[0018] Preferably, the first roller is fixed to the guide rod via a first rotating shaft, and the second roller is fixed to the mounting rod via a second rotating shaft.

[0019] Preferably, the length of the mounting rod is less than the length of the guide rod, so that the first roller and the second roller are spaced apart.

[0020] Compared to the aforementioned background technology, the tow pipe positioning device provided by this utility model includes: a first fixed crossbar and a second fixed crossbar arranged in parallel; two guide rods are vertically connected between the first fixed crossbar and the second fixed crossbar, and each guide rod is located at both ends of the first fixed crossbar along its length; a sliding sleeve is fitted on the outer periphery of each guide rod; a first elastic element is connected between the end of the sliding sleeve away from the first fixed crossbar and the second fixed crossbar; the sliding sleeve can slide on the outer periphery of the guide rod; a first roller is connected between the two sliding sleeves; two mounting rods are vertically arranged in the section of the first fixed crossbar between the two guide rods; a second roller is vertically arranged between the two mounting rods; a fixed bracket is rotatably connected to the end face of the second fixed crossbar away from the first fixed crossbar; the fixed bracket is used to fit on the outer periphery of the photovoltaic bracket; the fixed bracket fixes the tow pipe positioning device at a designated position on the photovoltaic bracket; a water supply pipe is extended between the first roller and the second roller; the first roller and the second roller clamp and fix the water supply pipe.

[0021] This application uses a fixed bracket to fix each tow pipe positioning device to the photovoltaic bracket, and uses a first roller and a second roller connected to the fixed bracket to clamp and fix the water supply pipe, so that the water supply pipe is set along the extension direction of the photovoltaic bracket. This prevents the water supply pipe from being obstructed or entangled by obstacles due to the complex structure of the photovoltaic bracket. When the drone drags the water supply pipe, the water supply pipe can slide in a preset direction to avoid interference from external objects. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This utility model provides a tow pipe positioning device; please refer to the appendix of the instruction manual. Figure 1 This application includes a first fixed crossbar 1 and a second fixed crossbar 2. The first fixed crossbar 1 is located above the second fixed crossbar 2 and the two are arranged parallel to each other. Two guide rods 4 are vertically inserted between the first fixed crossbar 1 and the second fixed crossbar 2. Each guide rod 4 is located at both ends of the first fixed crossbar 1 and the second fixed crossbar 2 along their length. A sliding sleeve 8 is fitted around the outer periphery of each guide rod 4. The sliding sleeve 8 slides along a predetermined direction of the guide rod 4. A first roller 6 is vertically arranged between the two sliding sleeves 8. Furthermore, two mounting rods 5 are also provided in the section of the first fixed crossbar 1 located between the two guide rods 4. Each mounting rod 5 is parallel to each guide rod 4. A second roller 7 is vertically connected between the two mounting rods 5. Preferably, the rotation axes of the first roller 6 and the second roller 7 are parallel to the first fixed crossbar 1. A first elastic element 9 is connected to one end of the sliding sleeve 8 near the second fixed crossbar 2. The first elastic element 9 is also sleeved on the outer periphery of the guide rod 4. The other end of the first elastic element 9 is fixedly connected to the second fixed crossbar 2. The first elastic element 9 is used to apply elastic force to each sliding sleeve 8. The sliding sleeve 8 being held can drive the first roller 6 and the second roller 7 to tightly clamp the water supply pipe, preventing the water supply pipe from swinging back and forth between the first roller 6 and the second roller 7. In addition, by compressing the first elastic element 9 to different degrees, the distance between the first roller 6 and the second roller 7 can be changed, so that they can clamp water supply pipes of different diameters. A fixed bracket 14 is rotatably connected to the end face of the second fixed crossbar 2 away from the first fixed crossbar 1. The fixed bracket 14 is specifically a rectangular frame, which is sleeved on the outside of the photovoltaic bracket 15 and can be locked in position with the photovoltaic bracket 15.

[0028] In the process of defining the extension direction of the water supply pipe through this application, a number of drag pipe positioning devices are installed on the photovoltaic bracket 15 by means of the fixed bracket 14, and the water supply pipe is clamped between the first roller 6 and the second roller 7. The second fixed crossbar 2, which is rotatably connected to the fixed bracket 14, can adjust the setting direction of the water supply pipe, so that this application can adapt to the complex setting environment of the photovoltaic bracket 15.

[0029] Please continue to refer to the instruction manual appendix. Figure 1 Mounting holes are provided at both ends of the first fixed crossbar 1 and the second fixed crossbar 2 along the length direction. Each guide rod 4 passes through the mounting holes and is inserted into the first fixed crossbar 1 and the second fixed crossbar 2. Both ends of the guide rod 4 are provided with screw heads, and the diameter of the screw heads is larger than the diameter of the mounting holes. The screw heads at both ends of the guide rod 4 abut against the end faces of the first fixed crossbar 1 and the second fixed crossbar 2 respectively to prevent the first fixed crossbar 1 and the second fixed crossbar 2 from detaching from the guide rod 4. Furthermore, the outer diameter of the sliding sleeve 8 is also larger than the diameter of the mounting holes. When the first elastic... After component 9 holds the sliding sleeve 8, the end of the sliding sleeve 8 abuts against the edge of the mounting hole to prevent the first fixed crossbar 1 from sliding down along the guide rod 4. Preferably, the length of the mounting rod 5 is less than the length of the guide rod 4. The second roller 7, which is fixed to the first fixed crossbar 1 by the mounting rod 5, is always spaced apart from the first roller 6, so that the two have space to clamp the water supply pipe. In addition, a relief groove 16 is provided on the side wall of the first fixed crossbar 1. The depth of the relief groove 16 is along the width direction of the first fixed crossbar 1. Preferably, the two guide rods 4 can specifically refer to a first guide rod and a second guide rod. The mounting hole for the second guide rod is connected to the relief groove 16, allowing the mounting hole to connect to the outside of the first fixed crossbar 1. In other words, the first fixed crossbar 1 with this structure has only one end through which the first guide rod passes. The operator can rotate the first fixed crossbar 1 around the first guide rod as a pivot, with the rotation direction opposite to the end of the relief groove 16. The second guide rod disengages from the relief groove 16, forming a rectangular frame composed of the guide rods 4, the first roller 6, and the first fixed crossbar 1. An opening is made at the top, allowing the operator to place the water supply pipe onto the first roller 6. Then, the first fixed crossbar 1 is rotated in the opposite direction to lock the water supply pipe between the guide rods 4. The first fixed crossbar 1 moves along with the second roller 7. With the clearance groove 16 aligned with the second guide rod, the second roller 7 presses down on the water supply pipe positioned above the first roller 6, compressing the first elastic element 9. The elastic force generated by the first elastic element 9 pushes against the first roller 6, making the clamping of the water supply pipe between the first roller 6 and the second roller 7 more secure.

[0030] Preferably, the diameter of the guide rod 4 is smaller than the diameter of the mounting hole, so that the side wall of the guide rod 4 is spaced apart from the side wall of the mounting hole, which facilitates the rotation of the first fixed crossbar 1 around the guide rod 4; a first rotating shaft is provided between each guide rod 4, and a second rotating shaft is provided between each mounting rod 5. The first rotating shaft passes through the first roller 6, and the second rotating shaft passes through the second roller 7, so that the first roller 6 and the second roller 7 can rotate around their own axes.

[0031] Furthermore, a connecting rod 10 is fixedly connected to the end face of the second fixed crossbar 2 facing away from the first fixed crossbar 1. Preferably, a through hole is provided on the end face of the second fixed crossbar 2, and the connecting rod 10 passes through the through hole. A connecting screw is coaxially provided at the end of the connecting rod 10. The diameter of the head of the connecting screw is larger than the diameter of the through hole. The head of the connecting bolt abuts against the end of the through hole to prevent the connecting bolt from sliding out of the through hole. The tail of the connecting bolt is vertically inserted into the third fixed crossbar 3, and the part of the connecting bolt that passes through the third fixed crossbar 3 is threadedly connected to a limiting sleeve 11. The diameter of the limiting sleeve 11 is larger than the diameter of the through hole. After the assembly of the connecting rod 10 and the third fixed crossbar 3 is completed, the upper end face of the limiting sleeve 11 abuts against the third fixed crossbar 3. That is, the connecting rod 10 suspends the third fixed crossbar 3 below the second fixed crossbar 2 through the limiting sleeve 11, and the third fixed crossbar 3 can rotate relative to the second fixed crossbar 2 with the connecting rod 10 as the rotation axis.

[0032] Positioning screws 12 are perpendicularly inserted at both ends of the third fixed crossbar 3 along its length. The head of the positioning screw 12 abuts against the end face of the third fixed crossbar 3, and the tail of the positioning screw 12 passes through the side wall of the fixed bracket 14. Preferably, a connecting plate is also provided on the outer side of the side wall of the fixed bracket 14 where the positioning screw 12 is connected. The end face of the connecting plate is provided with a threaded hole. That is, the positioning screw 12 is threadedly connected to the connecting plate while passing through the fixed bracket 14. The length of the positioning screw 12 extending into the fixed bracket 14 is adjusted by turning the positioning screw 12 so that the positioning screw 12 abuts against the light. The bottom surface of the groove of the photovoltaic bracket 15 and the inner wall of the fixed bracket 14 are tightly fitted to the photovoltaic bracket 15. The third fixed crossbar 3 is fixedly connected to the photovoltaic bracket 15 through the positioning screw 12. In addition, a second elastic member 13 is sleeved on the outer periphery of the positioning screw 12. The two ends of the second elastic member 13 abut against the third fixed crossbar 3 and the connecting plate, so that the two tend to move in opposite directions. This makes the positioning screw 12 tightly abut against the threaded surface of the threaded hole. By increasing the friction between the two, the positioning screw 12 is prevented from loosening, which would affect the positioning effect of the fixed bracket 14 and the photovoltaic bracket 15.

[0033] Preferably, the sidewall of the first roller 6 is a cylindrical surface, while the diameter of the second roller 7 gradually decreases towards the midpoint of its axis. In other words, the outline of the second roller 7 is arc-shaped. When the water supply pipe is clamped by the first roller 6 and the second roller 7, the water supply pipe is located in the recessed area of ​​the second roller 7, and the inclined walls on both sides of the water supply pipe restrict its sliding between the first roller 6 and the second roller 7.

[0034] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0035] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
