[0020] Firstly, for the fire extinguishing sand box: the fire extinguishing sand box is designed through innovative sealing components, and realizes rapid release of the fire extinguishing sand. When a fire occurs, the staff only needs to simply operate the driving part to make the sliding plate slide, and then the lower sand outlet can be quickly opened, so that the fire extinguishing sand automatically flows out to cover the fire source, the fire extinguishing response time is greatly shortened, and the fire extinguishing efficiency is effectively improved; compared with the traditional manual fire extinguishing mode, the fire extinguishing sand box does not need the staff to directly contact the fire source, and the safety risk of the staff in the fire extinguishing process is reduced. At the same time, the automatic operation reduces the participation of the operator, and further improves the safety of the on-site operation. The fire extinguishing sand box is rationally designed in structure, and the components are closely matched, so that the fire extinguishing sand box not only occupies a small space, but also is convenient for daily maintenance and replacement of the fire extinguishing sand. In particular, the ingenious cooperation between the sliding plate and the baffle makes the sealing and opening operation simple and fast, improves the reliability and service life of the equipment; compared with the complex pipeline fire extinguishing system, the fire extinguishing sand box is low in cost and easy to install, and the structure of the machine tool does not need to be greatly changed, so that the initial investment cost and the maintenance cost of the enterprise are reduced.

As an example, the cover plate 110 is threadedly connected with the box body 100, and in another embodiment, the cover plate 110 is slidingly matched with the box body 100, so that the cover plate 110 can close or open the sand storage groove 101, and it is convenient for the staff to add fire-fighting sand into the sand storage groove 101.
[0045] Optionally, the cross section of the sand storage groove 101 is in a trapezoidal structure, the lower base is shorter than the upper base, and the wall of the sand storage groove 101 forms an inclined slope, so that when the lower sand outlet 102 is opened, the fire-fighting sand in the sand storage groove 101 quickly slides under the action of gravity and flows out of the lower sand outlet 102, and thus the fire-fighting sand will not be blocked in the sand storage groove 101.
[0046] The closing assembly 200 is arranged in the box body 100, and the closing assembly 200 can close and open the lower sand outlet 102, so that the fire-fighting sand can flow out of the sand storage groove 101 or be stored in the sand storage groove 101. The closing assembly 200 includes a baffle 210 and a sliding plate 220, the baffle 210 is rotatably arranged in the box body 100 and can close or open the lower sand outlet 102, and the sliding plate 220 is slidably arranged in the box body 100 and located at the bottom of the baffle 210, the sliding plate 220 and the baffle 210 are in sliding cooperation, and the sliding plate 220 can support or space the baffle 210, so that the baffle 210 is fixed or rotated.
[0047] It should be noted that the sliding plate 220 is slidably arranged in the box body 100 and located at the bottom of the baffle 210, the sliding plate 220 and the baffle 210 are in sliding cooperation, when the sliding plate 220 and the baffle 210 are in contact, the sliding plate 220 provides a supporting force for the baffle 210, so that the baffle 210 is fixed and can close the lower sand outlet 102, when the sliding plate 220 slides to be not in contact with the baffle 210, the baffle 210 loses the supporting force and rotates under the action of gravity, so that the lower sand outlet 102 is opened and the fire-fighting sand stored in the sand storage groove 101 falls from the lower sand outlet 102.
[0048] Reference Figure 4 According to the first aspect of the utility model, the closing assembly 200 further includes a contact block 211, the baffle 210 is provided with the contact block 211, the sliding plate 220 is provided with an avoiding opening 221, and the avoiding opening 221 penetrates the sliding plate 220. The avoiding opening 221 has a plurality of avoiding openings, the baffle 210 has a plurality of baffles, and the baffle 210 corresponds to the avoiding opening 221 one by one.
[0049] When the baffle 210 needs to close the lower sand outlet 102, so that the fire-fighting sand can be stored in the sand storage groove 101, the sliding plate 220 slides to the staggered position of the contact block 211 and the avoiding opening 221, so that the contact block 211 and the sliding plate 220 are in contact, and since the sliding plate 220 is arranged at the bottom end of the baffle 210, the sliding plate 220 has a supporting force for the baffle 210 at this time, so that the baffle 210 is fixed to close the lower sand outlet 102.
[0050] When it is needed to open the lower sand opening 102 so that the fire-fighting sand can flow out from the lower sand opening 102, the sliding plate 220 slides to align the abutting block 211 with the avoiding opening 221, at this time, the sliding plate 220 is not in contact with the baffle 210, the baffle 210 loses the supporting force, and under the action of gravity, the baffle 210 rotates to open the lower sand opening 102, and the fire-fighting sand flows out. Wherein, the avoiding opening 221 and the abutting block 211 are matched in shape, so that when the abutting block 211 is aligned with the avoiding opening 221, the sliding plate 220 and the baffle 210 can be completely separated from each other, and then the baffle 210 loses the supporting force.
[0051] As an example, the abutting block 211 is integrally formed with the baffle 210, and a plurality of abutting blocks 211 are arranged at equal intervals, and correspondingly, a plurality of avoiding openings 221 are arranged at equal intervals on the sliding plate 220, and the number of the abutting blocks 211 is equal to the number of the avoiding openings 221.
