Description

Technical Field

[0001] This invention relates to the field of photovoltaic power plant technology, and in particular to a method for constructing a track for a mobile platform of a photovoltaic cleaning robot suitable for soft soil. Background Technology

[0002] In existing photovoltaic (PV) power generation projects, PV cleaning robots are typically deployed to clean the PV panels in a timely manner, ensuring power generation efficiency. A single PV cleaning robot usually needs to clean multiple rows of PV panels, requiring it to be able to move between these rows. To address this, a track is installed on the same side of the PV panels, and a mobile platform is mounted on the track, allowing the PV cleaning robot to move between the rows.

[0003] To ensure the stable movement of the photovoltaic cleaning robot between the photovoltaic panels and the mobile platform, it is crucial to guarantee that the mobile platform is aligned with each row of photovoltaic panels. However, many photovoltaic power generation projects are not built on flat ground, and in some projects constructed on soft soil, the photovoltaic modules may experience varying degrees of settlement. Consequently, the height and tilt angle of each row of photovoltaic panels differ, requiring the mobile platform's track to adapt to the condition of each row of panels. This ensures effective alignment between the mobile platform and each row, enabling the stable transfer of the photovoltaic cleaning robot. Summary of the Invention

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0046] This embodiment provides a method for constructing the track of a photovoltaic cleaning robot mobile platform suitable for soft soil, such as... Figure 1-3 As shown, the track 1 is located on one side of multiple rows of photovoltaic modules 2. Below the track 1, a height adjustment component 3, a boss 4, and a pile foundation 5 are sequentially arranged. Each row of photovoltaic modules 2 has two pile foundations 5 corresponding to its upper and lower edges. The track 1 includes multiple unit tracks 11. (As shown...) Figure 4 As shown, the method includes:

[0047] Step 100: Based on the lower edge height of each row of photovoltaic modules, pour two corresponding pile foundations to make the first height difference between the lower edge of each row of photovoltaic modules and its corresponding pile foundation equal;

[0048] Step 200: Measure the second height difference between the upper edge of each row of photovoltaic modules and its corresponding pile foundation;

[0049] Step 300: Based on the first height difference and the second height difference, cast a boss and a pre-embedded height adjustment component on each of the pile foundations;

[0050] Step 400: Install the rails on all height adjustment components;

[0051] Step 500: Fine-tune the height of the unit rail using the height adjustment component.

[0052] Specifically, in step 100, since the heights of each row of photovoltaic modules are not entirely the same, and the ground where the pile foundations are located also varies in elevation, it is necessary to pour corresponding pile foundations according to the specific conditions of each row of photovoltaic modules. Each row of photovoltaic modules corresponds to two pile foundations, with the two pile foundations corresponding to the upper and lower edges of the photovoltaic modules, respectively. This allows the upper and lower edges of the moving platform on the track to be aligned with the upper and lower edges of the photovoltaic modules by adjusting the pouring height of the bosses. To simplify the subsequent adjustment, the lower edge height of the photovoltaic modules is considered when pouring the pile foundations, ensuring that the lower edge of each pile foundation and its corresponding photovoltaic module is a preset fixed value. In this way, after pouring the bosses of the preset height, it can be ensured that the lower edge of the moving platform on the track can be aligned with the lower edge of each row of photovoltaic modules. Only the positional relationship between their upper edges needs to be adjusted, that is, only the height of the bosses corresponding to the upper edges of the photovoltaic modules in all pile foundations needs to be adjusted. If the pile foundation corresponding to the upper edge of the photovoltaic module is also directly poured to a height with a fixed height difference from the upper edge of the photovoltaic module, the pile foundation corresponding to the upper edge will need to be poured very high due to the large height difference between the upper and lower edges of the photovoltaic module, which will greatly increase the amount of concrete used and result in excessively high costs.

[0053] In step 200, since the pile foundation is cast according to the height of the lower edge of each row of photovoltaic modules, and the tilt angle of different photovoltaic modules is different, the height difference between the upper edge of different photovoltaic modules and their corresponding pile foundation is also different, and they need to be measured separately.

[0054] In step 300, since the height difference between the lower edge of each row of photovoltaic modules and its corresponding pile foundation is equal, the height of the protrusions on the pile foundation at the lower edge of each corresponding photovoltaic module is also consistent, resulting in higher casting efficiency. However, the height difference between the upper edge of each row of photovoltaic modules and its corresponding pile foundation is different, so it is necessary to cast protrusions of corresponding heights according to the second height difference. It should be noted that the height relationship between the height adjustment component and the protrusion is a fixed value, so there is no need to adjust the height relationship between it and the protrusion during casting. Figure 2 As shown, the height adjustment component 3 generally includes a screw 31, a track bracket 32, and an adjusting nut 33. The track bracket is installed on multiple screws via the adjusting nut, and the track is installed on the track bracket. To facilitate track installation and ensure installation stability, the track bracket is provided with a limiting groove to accommodate the track; that is, during installation, only the lower end of the track needs to be inserted into the limiting groove. To accommodate the tilt angle of the track, the track bracket is made of plastic to provide a certain degree of elasticity.

[0055] In step 400, there are two tracks, so two bosses and corresponding height adjustment components need to be poured on each pile foundation, and the two tracks are then built on the two sets of height adjustment components in sequence.

[0056] In step 500, through the above steps, the height of the track is basically adapted to the tilt angle of each row of photovoltaic modules. However, due to measurement errors and construction issues throughout the process, fine-tuning is still required using height adjustment devices to ensure accuracy. Specifically, fine-tuning can be performed by re-measuring the height difference between each part of the track and the upper and lower edges of its corresponding photovoltaic modules; alternatively, the moving platform can be moved along the track directly, and the alignment between the moving platform and each row of photovoltaic modules can be observed for fine-tuning.

[0057] One embodiment of mounting the rails on all height adjustment components may include:

[0058] Step 411: Install the unit rail on the height adjustment components of the two pile foundations corresponding to each row of photovoltaic modules;

[0059] Step 412: Select a connecting rail 12 of appropriate length based on the distance between two adjacent unit rail segments;

[0060] Step 413: Install the connecting rail 12 of the corresponding length between adjacent unit rails.

[0061] Specifically, such as Figure 5 As shown, each unit rail spans across two pile foundations in the same group, providing more stable support for the unit rail. However, considering factors such as production, processing, and transportation, the unit rail has a certain length limitation. In this embodiment, the unit rail cannot achieve full coverage, meaning there is still a certain gap between adjacent unit rails. Therefore, connecting rails of appropriate length need to be selected according to the gap distance for connection. These connecting rails are generally not purchased separately but are cut from the unit rails. The connection between the connecting rail and the unit rail can be achieved by welding. Therefore, while this embodiment ensures the stability of the rail support, it requires additional processing steps and also leads to waste of cutting materials.

[0062] Another embodiment of mounting the rails on all height adjustment components may include:

[0063] Step 421: Starting from one end, install the unit rail 11 sequentially on all height adjustment components, with the ends connected to the ground.

[0064] Specifically, such as Figure 6 As shown, with this installation method, different unit rails may be installed on two pile foundations in the same group, resulting in relatively poor stability. However, this avoids excessive cutting processes and saves materials. Generally, only the last section of the unit rail needs to be cut at the very end according to the required rail length.

[0065] In step 421, if the angle between adjacent unit rails is greater than a set value, the distance between the adjacent unit rails is increased, and a connecting rail 12 is installed between the adjacent unit rails so that the angle between the connecting rail and the two adjacent unit rail segments is not greater than the set value. If the angle between adjacent unit rails is too large, it will affect the smooth movement of the mobile platform. Therefore, it is necessary to increase the distance between the two unit rail segments and add a connecting rail to reduce track undulation.

[0066] like Figure 7 As shown, the step of casting a boss and pre-embedding a height adjustment component on each of the pile foundations according to the first height difference and the second height difference includes:

[0067] Step 301: Calculate the height of each boss based on the first height difference and the second height difference;

[0068] Step 302: Calculate the pre-embedded depth of the screw in the pile foundation based on the height of the boss;

[0069] Step 303: Cast the screw rod according to the pre-embedded depth;

[0070] Step 304: Cast the boss according to its height.

[0071] In step 301, the heights of all the protrusions along the lower edge of the photovoltaic module are consistent, requiring only sequential measurement. However, the heights of the protrusions along the upper edge of the photovoltaic module may differ, necessitating sequential measurement. Due to the varying protrusion heights, if both the protrusions and the bolts are cast together, a single formwork cannot be used, making construction relatively difficult. Therefore, considering that casting the protrusions is relatively simple, while the bolts require precise positioning, the casting and fixing of the bolts is prioritized.

[0072] In step 302, the pouring depth of each screw in the boss is consistent, but the height of each boss is different. Therefore, the pre-embedded depth of each screw in the pile foundation is also different. After calculating the pre-embedded depth of each screw in the pile foundation, the screw can be poured and fixed first.

[0073] In step 303, the screw is cast using the method described above. Figure 8 The positioning plate 6 shown has the same length as the pile foundation 5, and is provided with multiple screw positioning holes. The pile foundation 5 contains a casting groove 51, such as... Figure 9 As shown, this step specifically includes:

[0074] Step 3031: Install the multiple screws onto the positioning plate using the adjusting nut to ensure the accuracy of the screw positions. In this embodiment, each pile foundation is provided with two pouring grooves on the left and right, each pouring groove is used to pour a boss, each boss is provided with three screws, and a track bracket is installed on every three screws.

[0075] Step 3032: Based on the pre-embedded depth, adjust the length of the screw extending out of the positioning plate using the adjusting nut, i.e., the depth to which the screw needs to be pre-embedded into the pile foundation.

[0076] Step 3033: Place the screw rod into the casting groove until the positioning plate is in contact with the upper side of the pile foundation. At this point, the length of the screw rod in the casting groove is the required pre-embedded depth. Furthermore, the contact between the positioning plate and the upper side of the pile foundation ensures the verticality of the screw rod.

[0077] Step 3034: Pour into the pouring trough. The pouring does not need to completely fill the pouring trough to avoid pouring into the adjusting nut under the positioning plate.

[0078] Step 3035: After the cement has solidified, remove the positioning plate.

[0079] In step 304, after the concrete for casting the screw has solidified, bosses can be cast around the screw according to the height of each boss to ensure the fixing strength of the screw.

[0080] The above description is merely a preferred embodiment of the present invention, and is one implementation method based on the overall concept of the present invention. Furthermore, the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
