[0001] This invention relates to the field of storage and mobility technology, and in particular to a mobile coal yard enclosure device. Background Technology

[0002] A coal yard is a place for storing coal, usually an auxiliary facility of a coal-fired power plant. With the continuous improvement of coal production capacity, the increasingly stringent environmental protection policies, and the increasing awareness of environmental protection, the open-air coal storage method commonly used by coal production enterprises in the past is no longer suitable. Coal storage yards that meet the actual needs of enterprises must be adopted in order to ensure good economic, environmental and social benefits.

[0003] Due to space limitations, coal yards cannot accommodate fire lanes, resulting in limitations in fire prevention and control capabilities. If a fire breaks out in a coal yard, it will affect the access of fire trucks and the rescue efficiency of firefighters. Furthermore, in the event of a fire in a coal yard, firefighting mainly relies on personnel entering the site, where visibility and working conditions are extremely poor, making it impossible to guarantee the safety of workers.

Detailed Implementation

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1

[0030] Referring to Figures 1 to 5, the first embodiment of the present invention is provided. This embodiment provides a mobile coal yard enclosure device, which includes a storage component 100, a support rod 101, and multiple support rods 101 are provided.

[0031] A slide rail block 101a is provided on the end face of the support rod 101, a movable frame 102 is provided on the outer wall of the slide rail block 101a, and multiple movable frames 102 are provided; a first elastic member 103 is provided on the outer wall of two movable frames 102 and a shielding canopy 104 is provided on the outer wall of the movable frame 102.

[0032] The limiting component 200 includes a sleeve 201 disposed inside the slide block 101a, a limiting block 202 disposed inside the slide block 101a, a second elastic member 203 disposed on the outer wall of the limiting block 202, and a magnetic block 204 disposed at the other end of the second elastic member 203.

[0033] In this scheme, two rows of support rods 101 are fixedly arrayed on flat ground or a platform, and slide blocks 101a are fixedly installed on the upper end of the support rods 101. In this scheme, multiple movable frames 102 are provided, and the length of the movable frame 102 is greater than the distance between two slide blocks 101a, so as to prevent the movable frame 102 from falling off when it slides along the outer surface of the slide block 101a.

[0034] The first elastic element 103 can be an elastic rope, spring, etc. In this design, the first elastic element 103 is an elastic rope. Both ends of the first elastic element 103 are fixed to the outer wall of the movable frame 102. When the first movable frame 102 is pulled, multiple movable frames 102 behind it can be pulled simultaneously through the first elastic element 103. When there is no force to restrain the first movable frame 102, the first elastic element 103 will pull the movable frame 102 back to its initial position. The shield 104 is fixed to the outer surface of the two rows of movable frames 102. When the movable frame 102 is pulled, the shield 104 is also pulled. When the movable frame 102 is reset, the shield 104 is also retracted. The advantage of this design is that the amount of coal stored inside can be adjusted according to actual needs, and the shield 104 can be pulled to a suitable position to ensure internal ventilation and maintain a good working environment. Because of the small ventilation volume, problems such as strong coal smell and dust will occur inside the coal yard, resulting in a poor internal environment. It should be noted that the canopy 104 can be made of foldable air-supported membrane or tarpaulin.

[0035] When a fire occurs, the canopy 104 can be opened immediately. The existing technology of installing fire monitoring devices inside the coal yard is not detailed here. Simultaneously, a sleeve 201 is installed inside the track block 101a. Magnetic blocks 204 are fixedly installed on both sides of the sleeve 201. Magnetic blocks 204 are common commercially available devices that attach upon power; this is existing technology and will not be described further. Subsequently, two metal limiting blocks 202 are slidably installed inside the sleeve 201, with the ends of the two limiting blocks 202 that are close to each other being beveled. A second elastic element 203 is installed between the limiting blocks 202 and the magnetic blocks 204. In use, the magnetic blocks 204 are powered on, allowing... The two limiting blocks 202 are moved away from each other, and then the moving frame 102 is inserted into the sleeve 201, with the bottom of the moving frame 102 contacting the inclined surfaces of the two limiting blocks 202. The signal of the fire monitor is then connected to the power control terminal of the magnetic block 204. When a fire is detected, the magnetic block 204 is immediately de-energized, and the limiting blocks 202 are pushed closer to each other by the second elastic element 203. The moving frame 102 is pushed out of the sleeve 201, and then the first elastic element 103 is retracted, opening the canopy 104 and exposing the interior to the external environment. This allows fire-fighting equipment to quickly extinguish the fire from the outside, or provides a convenient and safe environment for rescue personnel to enter without the interference of dense smoke.

[0036] In summary, when in use, the foremost movable frame 102 is moved above the appropriate track block 101a, and then the movable frame 102 is inserted into the sleeve 201 to restrict its movement. If a fire occurs, the inclined surface of the limiting block 202 can push the movable frame 102 out of the sleeve 201, so that the canopy 104 can be opened quickly, turning the coal yard into a movable coal yard enclosure device. Using a fire detector, the device can monitor whether a fire has occurred, thereby enabling the canopy to be opened in time, providing a favorable environment for firefighting.

[0037] Example 2

[0038] Referring to Figures 1 to 7, the second embodiment of the present invention differs from the first embodiment in that it further includes an interceptor 105 at the bottom of the slide block 101a. The interceptor 105 is composed of multiple interceptor plates 105a, which are hinged together. The outer wall of the slide block 101a is provided with a first channel 101b.

[0039] In order to prevent the overall equipment from being affected by wind, rain or other factors during storage, an interceptor 105 is rotatably installed on the lower surface of each track block 101a. The interceptor 105 is composed of multiple interceptor plates 105a hinged together. When both interceptor plates 105a on both sides are unfolded, a closed door can be formed. When they are folded up, the interceptor 105 can be pushed between the two support rods 101 to fill the gap between the two support rods 101. The folded interceptor 105 is equivalent to a baffle in the prior art.

[0040] The slide block 101a has a threaded rod 106 inside, and a connecting cylinder 107 is provided on the outer wall of the threaded rod 106. The inner wall of the connecting cylinder 107 is provided with a thread that matches the threaded rod 106.

[0041] In this design, the threaded rod 106 passes through the slide rail blocks 101a in the same row, and one end of the threaded rod 106 is connected to a drive, which is a motor. Meanwhile, the outer wall of the threaded rod 106 is fitted with a connecting cylinder 107. In this design, the length of the connecting cylinder 107 is greater than the distance between the two slide rail blocks 101a.

[0042] It should be noted that this solution differs from Embodiment 1. In this solution, the sleeve 201 is fixedly installed on the surface of the connecting cylinder 107. The advantage of this is that the position of the movable frame 102 is not restricted. The movable frame 102 is first inserted into the sleeve 201. The movable frame 102 can slide along the inside of the first channel 101b, and its length is greater than the distance between the two slide rail blocks 101a. Therefore, when the movable frame 102 is first inserted into the sleeve 201, the movable frame 102 is equivalent to being connected to the connecting cylinder 107. When the threaded rod 106 rotates, the connecting cylinder 107 will move back and forth without being synchronously rotated by the threaded rod 106. Similarly, when a fire is detected, the magnetic block 204 is quickly de-energized, the limiting block 202 pushes the movable frame 102 out of the sleeve 201, and then the canopy 104 quickly retracts, creating a relatively suitable environment for rescue.

[0043] The sleeve 201 is provided with a first groove 201a through which the limiting block 202 can slide.

[0044] The first slide groove 201a extends horizontally through the sleeve 201. Magnetic blocks 204 are fixedly installed at the two openings of the first slide groove 201a. A second elastic element 203 is installed inside the first slide groove 201a. The two ends of the second elastic element 203 are respectively connected to the magnetic blocks 204 and the limiting blocks 202.

[0045] In summary, the motor can be controlled according to the amount of coal piled up to move the moving frame 102 to a suitable position. If the work for the day is completed, the interceptor 105 can be pulled at the suitable position to close the interior; alternatively, the moving frame 102 can be moved directly to the maximum position, and then the interceptor 105 can be pulled open to close the interior. It should be noted that the advantage of setting the interceptor 105 on the two support rods 101 is that one side can be opened during operation, allowing workers to enter directly from the side, or when a fire is detected, one side can be opened to extinguish the corresponding fire point directly from the outside. For specific locations, the side interceptor 105 can be replaced with a baffle of existing technology.

[0046] Example 3

[0047] Referring to Figures 1 to 7, this is the third embodiment of the present invention, which differs from the previous two embodiments in that: the outer wall of the slide block 101a is provided with a slide rail 101a-1, the inner wall of the moving frame 102 is provided with a first receiving groove 102a, and the first receiving groove 102a is provided with a ball 102a-1 that can slide along the surface of the slide rail 101a-1.

[0048] In this design, the slide rail 101a-1 is equivalent to having a track on the outer walls of both sides of the slide rail block 101a. It should be noted that the moving frame 102 in this design adopts a U-shaped structure with the opening facing downwards, and is fitted onto the outer surface of the track block 101a. Secondly, multiple first receiving grooves 102a are arrayed on the inner wall of the moving frame 102. The first receiving grooves 102a provide space for the ball 102a-1 to be loaded into the moving frame 102. More than half of the ball 102a-1 is located inside the first receiving groove 102a to prevent the ball 102a-1 from falling off when it rolls along the surface of the slide rail 101a-1.

[0049] Both ends of the connecting cylinder 107 are provided with sliding cylinders 205. The outer wall of the sliding cylinder 205 is provided with a first slider 205a and a sliding ring 206. The inner wall of the sliding ring 206 is provided with a first groove 206a. The two sides of the first groove 206a are connected with first arc surfaces 206a-1. The outer wall of the sliding ring 206 is provided with a first mounting block 206b that can slide along the first channel 101b. The first mounting block 206b is rotatably connected to a hinge rod 207. The hinge rod 207 is provided with a clearance groove 207a.

[0050] A sliding cylinder 205 with a radius smaller than that of the connecting cylinder 107 is fixedly installed at both ends of the connecting cylinder 107. A first slider 205a is fixedly installed on the outer wall of the sliding cylinder 205, which can be used in conjunction with the slip ring 206 on the outer wall of the sliding cylinder 205. In order to ensure normal operation of the equipment, a first mounting block 206b is fixedly installed on the outer surface of the slip ring 206. The first mounting block 206b can slide along the inside of the first channel 101b. The first mounting block 206b is rotatably connected to the hinge rod 207. During the rotation and crossing of the two hinge rods 207, they rotate along the inner wall of the other's relief groove 207a respectively to prevent the two hinge rods 207 from colliding.

[0051] A rotating shaft 208 is connected between the two hinge rods 207. A first limiting plate 208a is provided at one end of the rotating shaft 208 near the sleeve 201. A second arc surface 208a-1 is provided on the surface of the first limiting plate 208a.

[0052] In this design, both hinge rods 207 are rotatably connected to the rotating shaft 208. During use, pressing down on the moving frame 102 causes the two hinge rods 207 to rotate, pushing the two slip rings 206 away from each other. Simultaneously, the rotating shaft 208 is pushed into the sleeve 201. The difference lies in the fact that a first limiting plate 208a is fixedly installed on the lower surface of the rotating shaft 208, and the radius of the first limiting plate 208a is larger than that of the rotating shaft 208. The lower surface of the first limiting plate 208a has a second arc surface 208a-1. When the rotating shaft 208 slides downwards, the first limiting plate 208a pushes the two limiting blocks 202 to both sides. When the first limiting plate 208a slides past the limiting blocks 202, the second elastic... Part 203 pushes the limiting block 202 into the upper surface of the first limiting plate 208a, thus ensuring that the rotating shaft 208 will not fall off after entering the sleeve 201. In this state, the two hinge rods 207 are not parallel and have a certain angle. In the non-installed state, the end of the hinge rod 207 away from the first mounting block 206b is higher than the apex of the rotating shaft 208. The advantage is that the hinge rod 207 lifts the moving frame 102, and the moving frame 102 will not contact the rotating shaft 208. When the moving frame 102 moves downward, the moving frame 102 will push the hinge rod 207 to rotate. At the same time, it will push the slip ring 206 to move to both ends and continue to push the moving frame 102. The moving frame 102 will then start to contact the rotating shaft 208.

[0053] Unlike the previous embodiment, when a fire is detected, the magnetic block 204 is energized and will attract the limiting block 202, releasing the limitation block 202 from restricting the rotating shaft 208; the second arc surface 208a-1 is to allow the first slider 205a to better enter the first groove 206a.

[0054] The end of the rotating shaft 208 away from the first limiting plate 208a is provided with a second limiting plate 208b, and the moving frame 102 is provided with a through hole 102b through which the second limiting plate 208b can slide.

[0055] To better connect the movable frame 102 with the movable connecting cylinder 107, a through hole 102b is drilled on the surface of the movable frame 102. The size of the through hole 102b is adapted to the size of the second limiting plate 208b. When the movable frame 102 moves downward, it will push the hinge rod 207 to rotate. At the same time, the second limiting plate 208b will enter the through hole 102b. Because the rotating shaft 208 is restricted by the limiting block 202, it cannot move upward. Therefore, the movable frame 102 has no upward force at this time. So, when the threaded rod 106 is rotated to drive the connecting cylinder 107 to move, the movable frame 102 moves accordingly.

[0056] The outer wall of the slide 205 is fitted with a third elastic element 209.

[0057] A third elastic element 209, which is a compression spring, connects the slide cylinder 205 and the connecting cylinder 107. The advantage of this design is that when the hinge rod 207 pushes the slide cylinder 205, the slide cylinder 205 will pull the third elastic element 209. At the same time, the first slider 205a will enter the first groove 206a. At this time, the slip ring 206 is connected to the slide cylinder 205, which is also equivalent to being connected to the connecting cylinder 107. If the moving frame 102 is not installed properly and the limiting block 202 fails to lock the first limiting plate 208a, the third elastic element 209 will push the moving frame 102 upward, and at the same time, the moving frame 102 will disengage from the rotating shaft 208.

[0058] In summary, after installation, when in operation, the motor is started, driving the threaded rod 106 to rotate, which in turn moves the connecting cylinder 107. Subsequently, the ball bearing 102a-1 on the inner wall of the moving frame 102 slides along the inner wall of the slide rail 101a-1. When the fire monitor detects a fire, the magnetic block 204 is energized, separating the two limiting blocks 202 and releasing the restriction on the rotating shaft 208. Then, the third elastic element 209 begins to pull the slip rings 206 closer together, causing the first slider 205a to leave the first groove 206a. Simultaneously, the hinge rod 207, at the hinge point with the rotating shaft 208, moves upwards, and then the hinge rod 207 begins to push upwards. The movable frame 102 moves upward and disengages from the rotating shaft 208. The first elastic element 103 then pulls the movable frame 102 to quickly retract, closing the canopy 104 and opening the internal space. The fire extinguishing equipment can then directly extinguish the fire from above. If fire extinguishing equipment needs to enter, the open-air location will not suffer from dense smoke that obstructs visibility and affects operator work. If a fire breaks out inside the existing system and the space cannot be opened in time, the unburned coal gas and dense smoke will prevent the internal space from functioning properly. Additionally, if the internal space is insufficient, the fire extinguishing equipment may experience difficulty in movement or malfunction.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
