Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The purpose of this invention is to provide a slope-finding device for drainage ditches to solve the problems existing in the prior art. The bottom width of the slope-finding device can be adjusted to suit drainage ditches of different widths.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figures 1-4 As shown, this embodiment provides a slope-finding device for drainage ditches, which can be applied to slope finding of roof drainage ditches, especially for slope finding of drainage ditches on irregular roofs. It mainly includes a movable platform 1, with rollers 4 rotatably connected to both sides of the movable platform 1. The movable platform 1 can be placed in the drainage ditch and moved along the drainage ditch. It also includes an adjustment device, with the rollers 4 on both sides of the movable platform 1 connected to the movable platform 1 via the adjustment device. The adjustment device can adjust and lock the distance between the rollers 4 and the movable platform 1, so that the rollers 4 on both sides of the movable platform 1 can respectively contact the side walls of the drainage ditch. The movable platform 1 is also equipped with a marking assembly, which can mark lines on the roof surface on both sides of the top of the drainage ditch.

[0030] In this embodiment, an adjustment device is provided to adjust the distance between the roller 4 and the movable platform 1, thereby adjusting the width of the bottom of the slope-finding device. This is suitable for drainage ditches of different widths, allowing the rollers 4 on both sides to contact the sides of the drainage ditch. This prevents the sides from shifting during the pushing operation and increases the stability of the detection.

[0031] Furthermore, the marking component installed on the activity platform 1 can mark lines on the roof on both sides of the top of the drainage ditch, thereby recording each position of the drainage ditch during the slope finding process, which facilitates operation and reduces operation time.

[0032] In this embodiment, as Figure 1 and Figure 2As shown, the adjustment device includes an adjustment rod 2 and a positioning component. Each of the rollers 4 on both sides of the movable platform 1 is connected to the movable platform 1 through an adjustment rod 2. The adjustment rod 2 is parallel to the width direction of the movable platform 1 and can reciprocate along the width direction of the movable platform 1. The positioning component is provided on the movable platform 1 near the adjustment rod 2. The positioning component can lock the adjustment rod 2 after the corresponding adjustment rod 2 moves to a preset position.

[0033] In a preferred embodiment, the positioning component includes a movable block 9, which can move up and down along the side wall of the movable platform 1; wherein, the top of the adjusting rod 2 is provided with a slot 11, which extends along the width direction of the movable platform 1, and the bottom of the movable block 9 is correspondingly provided with a locking block 10, which can be engaged in the slot 11 to lock the adjusting rod 2, and the locking block 10 is preferably a rubber block.

[0034] In this embodiment, the positioning component further includes a fixing block 8, which is fixed to the side wall of the movable platform 1. The movable block 9 and the fixing block 8 are located above and below the adjusting rod 2, respectively. A through hole is formed between the movable block 9 and the fixing block 8 for the adjusting rod 2 to pass through.

[0035] The fixed block 8 has a vertically opening at its top, into which a connecting rod 13 is installed. The connecting rod 13 can slide up and down along the mounting hole, and its top is fixedly connected to the bottom of the movable block 9. A support plate 12 is provided at the bottom of the connecting rod 13. The support plate 12 is located in the mounting hole, and an annular boss is provided at the top opening of the mounting hole. The annular boss allows the connecting rod 13 to pass through and restricts the passage of the support plate 12. A spring 14 is provided between the support plate 12 and the annular boss. The spring 14 is sleeved on the connecting rod 13, and its bottom is fixedly connected to the support plate 12.

[0036] In this embodiment, through the combined use of the positioning component and the adjusting rod 2, when adjustment of the adjusting rod 2 is required, the user pulls the movable block 9. The movable block 9 drives the connecting rod 13 and the support plate 12 to move upward. The support plate 12 compresses the spring 14, causing it to deform and disengage the locking block 10 from the slot 11, thus releasing the adjusting rod 2. At this time, the user adjusts the position of the adjusting rod 2 according to the width of the drainage ditch. After adjustment, the movable block 9 is released, and the spring 14 drives the movable block 9 to reset. The locking block 10 then engages with the slot 11, locking the position of the adjusting rod 2. At this time, the rollers 4 on both sides contact the sides of the drainage ditch, thereby preventing lateral displacement during push detection and increasing detection stability.

[0037] In this embodiment, as Figure 4 As shown, movable grooves 19 are provided on both sides of the movable platform 1. The movable grooves 19 extend along the width direction of the movable platform 1, and sliding grooves 20 are provided on the side walls of the movable grooves 19 along their length direction. One end of the adjusting rod 2 extends into the movable groove 19 and is slidably installed in the corresponding sliding groove 20 through the slider 21. Through the cooperation of the sliding groove 20 and the slider 21, the adjusting rod 2 can slide along the width direction of the movable platform 1 and the rotation of the adjusting rod 2 can be restricted.

[0038] In this embodiment, the end of the adjusting rod 2 away from the movable platform 1 is connected to a connecting plate 3. The connecting plate 3 extends along the length direction of the movable platform 1, and the rollers 4 are rotatably mounted on both ends of the connecting plate 3.

[0039] In this embodiment, other adjustment devices can also be selected according to specific work needs. For example, a linear motor or hydraulic rod can be used as an adjustment device, which can automatically lock the roller 4 while driving it to move linearly.

[0040] In this embodiment, the marking assembly mainly includes a bracket 5, a telescopic rod 6, and a marking block 7. The bottom of the bracket 5 is fixedly connected to the top of the movable platform 1. A telescopic rod 6 is connected to each of the two sides of the top of the bracket 5. The telescopic rod 6 extends along the width direction of the movable platform 1, and the marking block 7 is installed at the end of the telescopic rod 6 away from the bracket 5. In this embodiment, the telescopic rod 6 can drive the marking block 7 to reciprocate along the width direction of the movable platform 1, adjusting the position of the marking block 7 according to different slopes. Moreover, the telescopic rod 6 can be a mechanical telescopic rod such as an electric actuator or a hydraulic rod, reducing the occurrence of extension and retraction during marking.

[0041] In this embodiment, a clamping assembly is provided at the end of the telescopic rod 6 away from the bracket 5, and the marking block 7 is clamped on the clamping assembly and extends out of the clamping assembly; wherein, as shown... Figure 3 As shown, the clamping assembly includes an upper clamping plate 15 and a lower clamping plate 16. The upper clamping plate 15 and the lower clamping plate 16 are located above and below the marking block 7, respectively. The lower clamping plate 16 is fixedly connected to the telescopic rod 6, and the upper clamping plate 15 and the lower clamping plate 16 are detachably connected.

[0042] Specifically, a friction block 17 is fixedly connected to the bottom of the upper clamping plate 15, and a friction groove 18 is correspondingly opened on the top of the lower clamping plate 16. The friction block 17 can be inserted into the friction groove 18 to clamp the scribing block 7, prevent displacement, and facilitate the disassembly and replacement of the scribing block 7; or, the upper clamping plate 15 and the lower clamping plate 16 can also be detachably connected by bolts or the like.

[0043] In this embodiment, the scribing block 7 is preferably powdered talc, which is not easily worn and wears out slowly during the scribing process.

[0044] In this embodiment, the movable platform 1 can also be connected to a pull rod, which allows the user to pull the pull rod to move the entire slope-finding device along the drainage ditch.

[0045] Furthermore, it should be noted that in this embodiment, the width direction of the movable platform 1 is parallel to the width direction of the drainage ditch, that is, perpendicular to the two side walls of the drainage ditch, and rollers 4 are installed on the two side surfaces of the movable platform 1 that are parallel to the two side walls of the drainage ditch.

[0046] The working process of the slope-finding device for the drainage ditch in this embodiment is as follows:

[0047] The user pulls the movable block 9, which moves the connecting rod 13 and the support plate 12 upwards. The support plate 12 compresses the spring 14, causing it to deform and disengage the locking block 10 from the slot 11, thus releasing the adjusting rod 2. At this point, the user adjusts the position of the adjusting rod 2 according to the width of the drainage ditch. After adjustment, the user releases the movable block 9, and the spring 14 causes the movable block 9 to return to its original position. The locking block 10 then engages with the slot 11, locking the position of the adjusting rod 2. At this point, the rollers 4 on both sides contact the sides of the drainage ditch.

[0048] The upper clamping plate 15 and the lower clamping plate 16 are engaged by friction blocks 17 and friction grooves 18 to secure the marking block 7. The telescopic rod 6 is adjusted according to different slopes. During the pushing operation, the slope is measured according to the position of the marking line and the position of the broken line. The specific measurement method is as follows:

[0049] In this embodiment, during construction of the drainage ditch slope-finding device, a broken-line measurement is performed according to the measurement length determined by the construction plan or the designed structural joint to ensure that the slope within the construction length meets the design requirements. After the rollers 4 on both sides of the drainage ditch slope-finding device contact the bottom sides of the drainage ditch, the rotation axis of the rollers 4 and the telescopic rod 6 are parallel to each other. The distance between the rollers 4 and the center of the support 5 on the movable platform 1 is measured, and the extension distance of the parallel telescopic rod 6 is determined (this extension distance refers to the distance between the end of the telescopic rod 6 and the center of the support 5). When the extension distance of the telescopic rod 6 is equal to the distance of the rollers 4, the sidewall of the drainage ditch is the same width as the bottom of the drainage ditch, and the slope of the sidewall of the drainage ditch is 90°. When the extension distance of the telescopic rod 6 is greater than the distance of the rollers 4, the width of the sidewall of the drainage ditch is greater than the width of the bottom of the drainage ditch, and the slope is found to both sides. The slope of the drainage ditch is measured by the extension distance of the telescopic rod 6.

[0050] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
