Description

Technical Field

[0001] The present invention relates to the technical field of pallet equipment, and in particular to a pallet. Background Art

[0002] In the power scrap warehouse, waste oil-immersed transformers, oil-immersed reactors and other power equipment containing waste oil are prone to leaking waste oil from the equipment after long-term use, rust, and transportation. If the equipment is placed directly on the ground, the waste oil will drip on the ground, making it difficult to collect and clean up. If the cleaning is not timely, there will be risks of fire safety hazards and even environmental pollution. If an ordinary anti-leakage pallet without an oil outlet is used, the transformer needs to be moved away from the equipment with a forklift to collect the leaked waste oil in the pallet, and the waste oil in the pallet cannot be collected quickly. If a pallet with multiple grooves and flat surfaces on the bottom is used, the waste oil cannot be concentrated in one place, and the collection and cleaning of the waste oil is difficult. Summary of the invention

[0003] The present invention aims to at least solve the technical problems in the prior art that, when using an ordinary anti-leakage tray without an oil outlet, the transformer needs to be moved away by a forklift to collect the waste oil leaking from the tray, and the waste oil in the tray cannot be collected quickly. When using a tray with multiple grooves and flat surfaces at the bottom, the waste oil cannot be collected in one place, and the oil collection and cleaning are difficult.

[0004] To this end, an object of the present invention is to provide a pallet, which includes a pallet body and a pallet cover plate covered on the pallet body, the pallet cover plate is provided with an oil leakage hole, the pallet body is provided with a drainage piece connected to the oil leakage hole, and the pallet body is also provided with an oil collecting port connected to the drainage piece.

[0005] In some embodiments, the oil collecting port is disposed at the center of the bottom of the tray body, and the drainage member includes a plurality of first drainage grooves disposed around the oil collecting port, wherein the first drainage grooves have a first drainage slope inclined downward toward the oil collecting port.

[0006] In some embodiments, the guide member includes a plurality of guide plates arranged around the oil collecting port, the first guide groove is formed between two adjacent guide plates, the top of the guide plate has a second guide slope, and the second guide slope is inclined downward in a direction close to the oil collecting port.

[0007] In some embodiments, the guide plate is formed to extend from the inner wall of the tray body toward the oil collecting port.

[0008] In some embodiments, a gap is formed between the drainage plate and the inner wall of the tray body to form a second drainage groove connected to the first drainage groove.

[0009] In some embodiments, a cover plate support is provided on the top of the guide plate to form an oil leakage space between the tray cover plate and the top of the guide plate.

[0010] In some embodiments, the plurality of first drainage grooves are arranged in a cross shape, an X shape, or a cross shape.

[0011] In some embodiments, a plurality of oil extraction holes are provided on the tray cover.

[0012] In some embodiments, the tray cover is a split structure.

[0013] In some embodiments, a plurality of the oil leakage holes are arranged in an array on the tray cover.

[0014] In some embodiments, the inclination angle of the first drainage slope is greater than the inclination angle of the second drainage slope.

[0015] A tray provided by an embodiment of the present invention has the following beneficial effects:

[0016] (1) The pallet provided in the embodiment of the present invention collects the oil dripping from the oil-immersed equipment into the interior of the pallet body after the oil dripping from the oil leakage hole of the pallet cover plate is dripped into the interior of the pallet body, thereby preventing the oil from dripping onto the ground and reducing the probability of safety hazards caused by oil leakage from the oil-immersed equipment;

[0017] (2) In the tray provided by the embodiment of the present invention, a drainage member formed by first drainage grooves and drainage plates of different heights is arranged in the tray body, and the first drainage grooves and drainage plates are arranged obliquely toward the central part of the tray body. The oil flowing from the tray cover plate into the tray body can be collected at the oil collecting holes under the guidance of the first drainage grooves and drainage plates and then be uniformly drawn away. The oil is collected in a partial area of ​​the tray body instead of on the entire surface of the tray body, thereby reducing the difficulty of cleaning the tray body.

[0018] (3) The tray provided in the embodiment of the present invention has an oil extraction hole on the tray cover plate, through which the oil is extracted. When the oil-immersed equipment does not need to be moved, the oil extraction pipe can be inserted into the tray to perform the oil extraction operation, thereby quickly collecting the waste oil dripping into the tray. Furthermore, the waste oil can be extracted at any time without being restricted by the heavy weight of the oil-immersed equipment that is difficult to remove from the tray.

[0034] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments claimed are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid obscuring the present invention with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0035] A first embodiment of the present invention provides a tray, such as Figure 1-Figure 6 As shown, the pallet includes a pallet body 1 and a pallet cover 2 covering the pallet body 1. The pallet cover 2 is provided with an oil leakage hole 21. The pallet body 1 has a storage space inside. The oil-immersed equipment is placed on the pallet. The oil leakage of the oil-immersed equipment can enter the internal storage space of the pallet body 1 along the oil leakage hole 21 under the action of gravity and be stored, thereby avoiding dripping on the ground and causing safety hazards.

[0036] like Figure 2 As shown, the pallet cover 2 is a split structure. Specifically, the pallet cover 2 includes a plurality of plate bodies 22 spliced ​​in sequence. For example, the pallet cover 2 includes two plate bodies 22. When in use, for a smaller oil-immersed device, if one of the plate bodies 22 is damaged, the oil-immersed device can be placed on the other plate body 22, without removing the oil-immersed device from the pallet and replacing it with a new pallet, thereby reducing the workload of maintenance and improving the utilization rate of the pallet.

[0037] Here, the multiple oil leakage holes 21 are arranged in an array on the pallet cover 2. By providing the multiple oil leakage holes 21 on the pallet cover 2, the flow rate of the oil into the interior of the pallet can be accelerated. The multiple oil leakage holes 21 are arranged in an array and are evenly distributed on the pallet cover 2, which is conducive to ensuring that all parts of the pallet cover 2 can stably leak oil into the interior of the pallet. In other embodiments, the oil leakage holes 21 can also be arranged in other forms on the pallet cover 2.

[0038] like Figure 3 and Figure 4 As shown, in this embodiment, an oil collecting port 11 is arranged at the center of the bottom of the tray body 1, and a guide member 12 connected to the oil leakage hole 21 is arranged in the tray body 1. The oil entering the tray body 1 from the oil leakage hole 21 of the tray cover 2 is collected at the oil collecting port 11 under the guidance of the guide member 12.

[0039] Specifically, the guide member 12 includes a guide plate 121 and a first guide groove 122 arranged around the oil collecting port 11, wherein the guide plate 121 and the first guide groove 122 are arranged in a plurality along the circumference of the tray body 1. A first guide groove 122 is formed between two adjacent guide plates 121. A portion of the oil leaking from the tray cover plate 2 into the tray body 1 falls into the first guide groove 122 along the oil leakage hole 21, and the oil in the plurality of first guide grooves 122 is collected at the oil collecting port 11. Another portion of the oil leaking from the tray cover plate 2 into the tray body 1 falls along the oil leakage hole 21 on the top of the guide plate 121, and then flows to the first guide groove 122 under the action of gravity and then is collected at the oil collecting port 11, that is, the oil dripping into the first guide groove 122 and the guide plate 121 will eventually be collected at the oil collecting port 11. The height of the drainage plate 121 here is higher than the height of the first drainage groove 122, forming a staggered layout inside the tray body 1. The oil is distributed in a larger area inside the tray body 1, and multiple temporary storage areas are formed inside the tray body 1. The oil is distributed more evenly in the tray, and the oil-immersed equipment will not easily tip over due to unstable center of gravity.

[0040] Furthermore, the first drainage groove 122 has a first drainage slope 123 that slopes downward toward the oil collecting port 11. The top of the drainage plate 121 has a second drainage slope 124, and the second drainage slope 124 slopes downward in a direction close to the oil collecting port 11. The diversion effect is achieved by setting the first drainage slope 123 and the second drainage slope 124, which is conducive to the oil to quickly gather from the first drainage slope 123 and the second drainage slope 124 to the oil collecting port 11 under the action of gravity, thereby increasing the flow rate of the oil, and the oil is not easy to gather at the drainage plate 121 and the first drainage groove 122. Instead, it flows along the first drainage groove 122 and the drainage plate 121 into the middle oil collecting port 11 to prevent leakage to the outside of the tray. In some embodiments, multiple first drainage grooves 122 are arranged in a cross shape, an X shape, or a rice shape, and the first drainage grooves 122 are distributed more evenly in the tray body 1.

[0041] Furthermore, since the oil dripping on the drainage plate 121 will first flow into the first drainage groove 122 and then gather at the oil collecting port 11, the liquid in the first drainage groove 122 is prone to aggregation. The inclination angle of the first drainage slope 123 is set to be greater than the inclination angle of the second drainage slope 124. The drainage speed of the first drainage slope 123 is faster, which prompts the oil to flow quickly to the oil collecting port 11.

[0042] In this embodiment, the guide plate 121 extends from the inner wall of the tray body 1 toward the oil collecting port 11 , and the guide plate 121 supports the tray body 1 , which is beneficial to improving the overall strength of the tray body 1 and the anti-deformation ability of the tray body 1 .

[0043] In another embodiment, Figure 5 As shown, there is a gap between the guide plate 121 and the inner wall of the tray body 1, forming a second guide groove 125 connected to the first guide groove 122. The second guide groove 125 is set between the inner wall of the tray body 1 and the guide plate 121, which is beneficial for the oil in the area close to the edge of the tray body 1 to flow along the second guide groove 125 to the first guide groove 122, and then gather to the oil collecting port 11, and will not gather at the connection between the guide plate 121 and the tray body 1. The criss-cross form of the first guide groove 122 and the second guide groove 125 here is beneficial for the oil to leak from the tray cover 2 to different areas of the first guide groove 122 and the second guide groove 125, and the oil is more evenly distributed before being gathered to the oil collecting port 11.

[0044] In this embodiment, the oil-immersed device is placed on the tray cover 2, and the pressure on the tray cover 2 is relatively large. Therefore, a cover support 3 is provided on the top of the drain plate 121. The cover support 3 contacts the tray cover 2 and the drain plate 121 respectively, supports the tray cover 2, and improves the strength of the tray cover 2. In addition, the cover support 3 can form an oil leakage space between the tray cover 2 and the top of the drain plate 121. The oil leakage space is the gap formed between the top of the tray cover 2 and the drain plate 121. The contact between the cover support 3 and the tray cover 2 will make the contact area between the tray cover 2 and the drain plate 121 smaller. Compared with not providing the cover support 3, the oil dripping from the oil leakage hole 21 into the tray body 1 will not form an oil accumulation area between the tray cover 2 and the drain plate 121. The oil can smoothly enter the first drain groove 122 along the oil leakage space, thereby increasing the flow rate of the oil in the tray body 1.

[0045] Furthermore, the pallet is made of metal material, which takes advantage of the high hardness and strength of the metal and improves the service life of the pallet. The pallet cover 2 is provided with a plurality of oil extraction holes 23. The oil extraction holes 23 are connected to the oil extraction device, through which the oil in the pallet cover 2 can be extracted, without the need to lift the heavy pallet to dump the oil inside; when waste equipment such as oil-immersed transformers, oil-immersed reactors, and oil drums do not need to be moved, the oil extraction pipe can be extended into the interior of the pallet, thereby quickly collecting the waste oil dripping from the pallet, saving time and effort. In order to better clean up the accumulated oil leakage, three oil extraction holes 23 are reserved on the top panel of the pallet to improve the oil extraction efficiency. It is also possible to lift the pallet cover 2 and extract the waste oil after the equipment is shipped out of the warehouse (moved away from the pallet).

[0046] Furthermore, the oil extraction hole 23 is arranged at the joint of the plate body 22 of the tray cover 2, so that even if one of the plate bodies 22 is damaged, the oil extraction operation is not affected.

[0047] In this embodiment, if Figure 1-Figure 4As shown, a plurality of supports 4 are arranged below the pallet body 1, and the supports 4 support the pallet body 1. At the same time, there is a gap between the supports 4 and the ground, and when carrying the pallet, the pallet can be operated in the gap by using a carrying tool, which is convenient and quick to operate. The supports 4 are arranged as a solid structure, which can improve the supporting performance of the pallet for the oil-immersed equipment, and the pallet is not easily deformed.

[0048] In another embodiment, a liquid level detection device is provided in the tray body 1, an alarm is provided outside the tray body 1, the liquid level detection device is connected to the controller, the controller is connected to the alarm, and the controller is configured so that when the liquid level detection device reaches a preset threshold, the controller sends a signal to the alarm to prompt that the liquid level in the tray body 1 is high and the tray needs to be cleaned of oil. The operator can connect the oil pumping device to the oil pumping hole 23 to perform the oil pumping operation according to the prompt of the alarm.

[0049] Furthermore, if Figure 6 As shown, the support 4 has a hollow cavity 41, and an adjustment plate 42 is arranged in the hollow cavity 41. A rotating shaft 43 rotatably connected to the adjusting plate 42 is arranged on the support 4, and a driving member is arranged at one end of the rotating shaft 43. The driving member passes through the support 4 and is arranged on the outer side of the support 4. Specifically, the driving member can be set as a handle. When a force is applied to the handle, the handle will drive the rotating shaft 43 to rotate, and the adjusting plate 42 will be switched between the first working state and the second working state. When the adjusting plate 42 is in the first working state, a liquid inlet channel is formed between the tray body 1 and the support 4, and the oil flows from the tray body 1 to the liquid inlet channel for storage; when the adjusting plate 42 is in the second working state, the tray body 1 and the support 4 are isolated from each other, and the oil in the tray body 1 will not enter the hollow cavity 41 in the support 4. At this time, the support 4 only plays a supporting role.

[0050] Furthermore, the support 4 is a structure whose diameter gradually decreases from top to bottom. The driving member drives the adjustment plate 42 to move upward to open the liquid inlet channel between the adjustment plate 42 and the support 4. The driving member drives the adjustment plate 42 to move downward. Since the diameter of the support 4 is thinner at the bottom, the adjustment plate 42 will be stuck on the inner wall of the support 4, isolating the tray body 1 and the support 4 from each other.

[0051] Among them, when the liquid level detection device detects that the liquid level in the pallet body 1 reaches a preset threshold value, it means that the oil level in the pallet is high. If the pallet continues to work, there is a risk of oil overflowing from the oil leakage hole 21 on the pallet cover 2. At this time, it is necessary to adjust the adjustment plate 42 to the first working state through the drive member, and enable the temporary oil storage function of the support 4. If the liquid level in the pallet does not reach the preset threshold value, it means that the oil level in the pallet has not reached the dangerous boundary value, and the adjustment plate 42 can remain in the second working state.

[0052] Furthermore, an oil outlet 45 is provided on the lower side of the side of the support 4, and a sealing cover or a valve is provided at the oil outlet 45. When the oil in the support 4 needs to be discharged, the sealing cover or the valve is opened, and the oil in the support 4 can flow out from the oil outlet 45 without lifting the tray and tipping it.
