Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1:

[0029] Reference Figures 1-5 A coal sample storage device for power plants, comprising:

[0030] Placement rack 1;

[0031] A chute 101 is provided on the shelf 1;

[0032] Slider 3 is slidably connected in slide groove 101;

[0033] Place box 2, which is fixedly connected to slider 3;

[0034] The partition 202 is fixedly connected in the placement box 2, and multiple sets of partitions 202 are evenly arranged in the placement box 2.

[0035] Reference Figure 1 , Figure 2 A handle 201 is fixedly connected to the placement box 2, which makes it easier for staff to pull out the placement box 2.

[0036] The placement rack 1 has a sliding cavity 6, in which a first sliding plug 601 is slidably connected. A first driving rod 6011 is fixedly connected to the first sliding plug 601. A support plate 5 is fixedly connected to the end of the first driving rod 6011 away from the first sliding plug 601. The support plate 5 is attached to the bottom wall of the placement box 2.

[0037] A drive cylinder 4 is fixedly connected in the slide 101, and an air supply pipe 405 is fixedly connected to the side wall of the drive cylinder 4. The end of the air supply pipe 405 away from the drive cylinder 4 is connected to the slide cavity 6.

[0038] A second sliding plug 401 is slidably connected in the drive cylinder 4, and a second drive rod 404 is fixedly connected to the second sliding plug 401. The end of the second drive rod 404 away from the second sliding plug 401 is fixedly connected to the slider 3.

[0039] A first spring 602 is fixedly connected to the first slide plug 601, and the end of the first spring 602 away from the first slide plug 601 is fixedly connected to the bottom wall of the slide cavity 6.

[0040] Reference Figure 4 , Figure 5 The first spring 602, which is provided on the first slide 601, enables the first slide 601 to be quickly reset.

[0041] A second spring 403 is fixedly connected to the second slide 401, and the end of the second spring 403 away from the second slide 401 is fixedly connected to the bottom wall of the drive cylinder 4.

[0042] Reference Figure 4 , Figure 5 The second spring 403, which is provided on the second slide 401, enables the second slide 401 to be quickly reset.

[0043] An air inlet pipe 402 is fixedly connected to the side wall of the drive cylinder 4, and a one-way valve is provided on both the air inlet pipe 402 and the air delivery pipe 405.

[0044] The bottom of the placement rack 1 is fixedly connected to a pressure relief pipe 603, which is connected to the sliding cavity 6.

[0045] It should be noted that the pressure relief pipe 603 is equipped with a commercially available pressure relief valve. By opening the pressure relief valve, the gas in the slide cavity 6 can be quickly released, which facilitates the pushback of the placement box 2.

[0046] Reference Figure 1 During storage, the coal sample to be stored is placed in the storage box 2, and the storage rack 1 is placed in a storage room without a heat source;

[0047] Reference Figures 1-5 When it is necessary to remove the coal sample to be tested, the staff arrives at the corresponding placement rack 1 and manually pulls the handle 201 to pull out the placement box 2. When the placement box 2 is pulled out, it will cause the slider 3 to slide. The sliding of the slider 3 will simultaneously pull the second drive rod 404 to move. The movement of the second drive rod 404 will pull the second sliding plug 401 fixedly connected to it to slide. The sliding of the second sliding plug 401 will squeeze the gas in the drive cylinder 4. After being squeezed, the gas in the drive cylinder 4 will enter the sliding cavity 6 through the gas supply pipe 405. The gas entering the sliding cavity 6 will push the first sliding plug 601 to slide. The sliding of the first sliding plug 601 will push the first drive rod 6011 to slide. The movement of the first drive rod 6011 will simultaneously drive the tray 5 to extend. The extended tray 5 can support the sliding placement box 2, and the staff can then manually remove the coal sample placed in the placement box 2.

[0048] After the staff takes out the coal sample to be taken, the staff manually pushes the placement box 2 and then retracts the placement box 2. When the placement box 2 is pushed back, the slider 3 slides back to its original position. The retraction of the slider 3 will simultaneously push the second drive rod 404 to its original position. The retraction of the second drive rod 404 will push the second sliding plug 401 to its original position. Then, outside air is drawn through the air inlet pipe 402 to replenish the gas in the drive cylinder 4 for the next use.

[0049] This device allows the tray 5 to be extended simultaneously when the placement box 2 is pulled, thereby supporting the extended placement box 2 and providing support to ensure the stability of the placement box 2 after it is extended. It also eliminates the need for manual assistance in lifting the placement box 2, making the operation more labor-saving and portable.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
