DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Embodiment one: please refer to Figure 1 - Figure 5 A loader counterweight drainage device, comprising a loader counterweight body 1, the loader counterweight body 1 is provided with a bench board 3 for draining the entire loader counterweight body 1, the loader counterweight body 1 is provided with a buckle assembly 2 for fixing the door, the buckle assembly 2 can fix the door, avoid the door from being shaken back and forth by the vibration of the loader when working, so that rainwater enters the loader counterweight, the loader counterweight body 1 is provided with a drainage assembly 4 for draining the door gap, the drainage assembly 4 can avoid a little water from entering the loader counterweight body 1 from the door gap, so as to cause damage to the generator.

[0024] The buckle assembly 2 comprises an outlet 203 and a first chamber 24 opened on the side wall of the loader counterweight body 1, two sleeves 21 are fixedly installed on the outlet 203, an access door 22 is rotatably installed between the two sleeves 21, a handle 23 is fixedly installed on the side wall of the access door 22, a drainage plate 25 is fixedly installed on the first chamber 24, a second chamber 26 and a third chamber 27 are opened on the drainage plate 25, two mounting blocks 28 are fixedly installed on the side wall of the access door 22, mounting grooves 29 are opened on the two mounting blocks 28, an arc block 201 is slidingly installed on the mounting groove 29, and a spring 202 is arranged between the arc block 201 and the mounting groove 29.

[0025] The drainage assembly 4 comprises a first drainage groove 41 formed in the upper end of the drainage plate 25, vertical drainage grooves 42 formed in the two ends of the drainage plate 25, and a second drainage groove 43 formed in the lower end of the drainage plate 25, wherein the first drainage groove 41 and the second drainage groove 43 are both designed to be higher in the middle and lower at the two sides, so as to drain the accumulated water faster, and the two ends of the second drainage groove 43 are both provided with water outlet grooves 44.

[0026] The size of the second chamber 26 is larger than that of the mounting block 28, so that the mounting block 28 can enter the second chamber 26 when rotating, thereby enabling the arc-shaped block 201 to enter the third chamber 27, and limiting the maintenance door 22.

[0027] The arc of the arc-shaped block 201 is perpendicular to the maintenance door 22, and can enable the maintenance door 22 to be smoothly opened when the handle 23 is forced.

[0028] The first drainage groove 41, the vertical drainage grooves 42 and the second drainage groove 43 are all corresponding to the four sides of the outlet 203, so as to avoid rainwater from entering the first chamber 24 through the gap of the maintenance door 22, thereby avoiding damage to the engine.

[0029] In the present embodiment: first, the maintenance door 22 is rotated towards the outlet 203, at this time the drainage plate 25 extrudes the arc-shaped block 201, so that the arc-shaped block 201 is extruded into the mounting groove 29, then the mounting block 28 enters the second chamber 26, at this time the arc-shaped block 201 enters the third chamber 27 through the action of the spring 202, so that the maintenance door 22 is attached to the outlet 203, and rainwater can also be prevented from entering the weight of the loader during the jolting of the loader, but when the rain is too heavy, some rainwater will inevitably penetrate into the first chamber 24 through the gap of the maintenance door 22, at this time the rainwater entering from the gap in the upper end of the maintenance door 22 will flow into the first drainage groove 41, because the first drainage groove 41 is located at the gap and the first drainage groove 41 is designed to be higher in the middle and lower at the two sides, at this time the rainwater will flow along the slope to the vertical drainage grooves 42 on both sides, and finally be drained from the loader weight body 1 through the water outlet grooves 44, the rainwater entering from the gap in the lower end of the maintenance door 22 will flow into the second drainage groove 43, and the second drainage groove 43 is also designed to be higher in the middle and lower at the two sides, at this time the rainwater will flow along the slope to the water outlet grooves 44 on both sides to drain the loader weight body 1, and through this design, the sealing gasket sealing water can be abandoned, and the aging of the sealing gasket over a long period of time and the reduction of the water sealing effect of the sealing gasket can be avoided.

[0030] Embodiment two: the present embodiment is an improvement based on embodiment one, and the specific improvement will be described with reference to Figure 6The slope board 3 is designed with a 2% slope, and the slope board 3 is designed with a cornice, so that rainwater can be drained from the middle to both sides, and rainwater can not flow along the side wall of the loader weight body 1 to the first chamber 24 through the gap of the maintenance door 22, thereby avoiding damage to the generator.

[0031] In the embodiment: when it rains, rainwater will fall on the slope board 3, because the slope board 3 is designed with a 2% slope, so that rainwater can be drained from the middle to both sides, and the loader weight body 1 is not filled with water, thereby avoiding water leakage, and the slope board 3 is designed with a cornice, so that rainwater can not flow along the side wall of the loader weight body 1 to the first chamber 24 through the gap of the maintenance door 22, thereby avoiding damage to the generator.
