DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will be further described in detail in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0021] The specific implementation of the utility model will be described in detail in combination with specific examples.

[0022] The utility model discloses a kind of portable isolation protective cover of coal mine electromechanical equipment, portable isolation protective cover of coal mine electromechanical equipment includes: main support frame 1;Two sides of main support frame 1 are connected with telescopic cover 11, and the side of two telescopic covers 11 away from main support frame 1 is connected with auxiliary support frame 12;Wherein, located at the top and both sides of two main support frames 1 are provided with folding assembly, and two telescopic covers 11 can be shrunk by folding assembly;Two auxiliary support frames 12 are provided with shielding assembly, and auxiliary support frame 12 can be sealed by shielding assembly.

[0023] It should be noted that: the main support frame 1 is the main support structure of the whole isolation protective cover, and the main support frame 1 plays a key load bearing role. The telescopic cover 11 is connected to the two sides of the main support frame 1 respectively, and is a key component for realizing flexible covering of the protective cover on different sizes of electromechanical equipment. The telescopic cover 11 is made of a material with certain flexibility and wear resistance, for example, special canvas that is fireproof, dustproof and tear-resistant. The telescopic principle of the telescopic cover 11 is similar to that of a foldable shutter structure, and the telescopic cover 11 can be smoothly stretched and contracted under the action of the folding and unfolding assembly. When it is necessary to protect larger size electromechanical equipment, the telescopic cover 11 can be stretched outward by means of the folding and unfolding assembly to increase the coverage range of the protective cover. When the equipment is small in size or needs to be maintained and repaired, the telescopic cover 11 can be retracted by means of the folding and unfolding assembly, which is convenient for operation. The auxiliary support frame 12 is located on the side of the telescopic cover 11 away from the main support frame 1, and provides a mounting base for the shielding assembly. The shielding assembly is installed in the two auxiliary support frames 12, and the main function of the shielding assembly is to seal the auxiliary support frame 12 to prevent dust and water vapor in the coal mine from entering the inside of the electromechanical equipment.

[0024] In the embodiment of the utility model, folding and unfolding assembly includes with main support frame 1 top connection's main support seat 2, and two main support seat 2's both sides are connected with first slide cylinder 21, two first slide cylinder 21 relative far away one end's inside are all slidably connected with second slide cylinder 22, two second slide cylinder 22 relative far away one end's inside are all slidably connected third slide cylinder 23, two third slide cylinder 23 relative far away one end are all connected with auxiliary support seat 24, two auxiliary support seat 24 are installed at the top of auxiliary support frame 12 respectively, first slide cylinder 21 is close to second slide cylinder 22 one end's outside rotationally connected with fixed nut 25, auxiliary support seat 24 is close to second slide cylinder 22 one side installation with fixed nut 25 corresponding fixed screw 26, fixed screw 26 is located at the outside of third slide cylinder 23.

[0025] It needs to be explained that: two main support seats 2 are connected with first sliding cylinders 21 on both sides, which mainly provide guidance and sliding track for subsequent sliding cylinders. The first sliding cylinder 21 is a hollow cylindrical structure, which is smooth inside, so that the second sliding cylinder 22 matched with it can smoothly slide inside. The inner side of the opposite end of the two second sliding cylinders 22 is slidably connected in the first sliding cylinder 21, which plays an intermediate transition role in the extension and retraction process of the whole retractable assembly. The outer diameter of the second sliding cylinder 22 is slightly smaller than the inner diameter of the first sliding cylinder 21, and the two form a precise sliding fit. During the extension and retraction operation, the second sliding cylinder 22 can smoothly slide in the first sliding cylinder 21 along the axial direction, so as to adjust the coverage range of the protective cover. The opposite ends of the two third sliding cylinders 23 are slidably connected in the second sliding cylinder 22, and the opposite ends thereof are connected with the auxiliary support seats 24. The third sliding cylinder 23 is also a hollow cylindrical structure, which is similar to the second sliding cylinder 22, and forms a precise sliding fit with the second sliding cylinder 22, further increasing the extension and retraction length of the retractable assembly. Through the step-by-step nested sliding of the first sliding cylinder 21, the second sliding cylinder 22 and the third sliding cylinder 23, the extension and retraction adjustment of the retractable assembly in a large range is realized. The two auxiliary support seats 24 are installed at the top of the auxiliary support frame 12, which are the key components for connecting the retractable assembly and the auxiliary support frame 12. The auxiliary support seat 24 transmits the extension and retraction movement of the retractable assembly to the auxiliary support frame 12 through the connection with the third sliding cylinder 23, so as to drive the extension and contraction of the telescopic cover 11. The outer side of the end close to the second sliding cylinder 22 of the first sliding cylinder 21 is rotatably connected with a fixed nut 25. The fixed nut 25 is used in cooperation with a fixed screw 26 to lock the extension and retraction position of the sliding cylinder when it is necessary to fix the position of the sliding cylinder, so as to limit the sliding of the second sliding cylinder 22 in the first sliding cylinder 21. It is ensured that the protective cover will not accidentally extend and retract during use due to external force and other factors.

[0026] In the embodiment of the utility model, the shielding assembly includes a winding roller 3 rotatably connected to the inner wall top of the auxiliary support frame 12, and the outer side of the winding roller 3 is wound with a shielding cloth 31, the inner side of the auxiliary support frame 12 is provided with a sliding groove for the shielding cloth 31 to pass through, the top of one side of the auxiliary support frame 12 is provided with a driving rotating wheel 32 for driving the winding roller 3 to rotate, the inner wall of the auxiliary support frame 12 is connected with a sliding rod 33 on both sides, and the outer side of the two sliding rods 33 is slidably connected with a counterweight 34, and the opposite side close to the bottom of the two counterweights 34 is connected with the shielding cloth 31.

[0027] It should be noted that: the top of the inner side wall of the secondary support frame 12 is rotatably connected with the winding roller 3, which is the core component of the shielding assembly for controlling the winding and unwinding of the shielding cloth 31. The shielding cloth 31 is wound on the outer side of the winding roller 3, which is the part directly playing the sealing shielding role. When the winding roller 3 rotates, the shielding cloth 31 will be wound or unwound accordingly, covering or exposing the part to be protected through the sliding groove formed in the inner side of the secondary support frame 12. The design of the sliding groove not only provides guidance for the movement of the shielding cloth 31, ensuring that it will not deviate or jam during winding and unwinding, but also can protect the shielding cloth 31 to a certain extent, preventing its edges from being scratched and damaged by the outside world. The driving rotating wheel 32 is installed on the top of one side of the secondary support frame 12 and is used to drive the winding roller 3 to rotate. Since the shielding cloth 31 only needs to be wound up during installation, no locking mechanism is provided for locking. The inner walls of the secondary support frame 12 are connected with sliding rods 33 on both sides. The sliding rods 33 provide sliding tracks for the counterweight blocks 34, ensuring that the counterweight blocks 34 can stably move up and down in the vertical direction. The sides close to each other of the two counterweight blocks 34 are connected with the bottom sides of the shielding cloth 31 respectively. The main function of the counterweight blocks 34 is to use their own gravity to make the shielding cloth 31 maintain a vertical and tight state in the unwound state, so as to better realize the sealing effect. When the shielding cloth 31 is unwound, the counterweight blocks 34 slide downward along the sliding rods 33 under the action of gravity, stretching the bottom of the shielding cloth 31 downward, avoiding the slackening or wrinkling of the shielding cloth 31, and ensuring that it can tightly fit on the inner side of the secondary support frame 12, effectively blocking the invasion of impurities such as dust and water vapor. The through hole 35 is formed in the bottom side of the shielding cloth 31. This design is to meet the specific use requirements, such as in some cases, it may be necessary to lead the lines or pipelines of the equipment from a specific position. A plurality of plugging pads 36 are installed at the inner axial center of the through hole 35. The plugging pads 36 are made of elastic and sealing materials, such as rubber. Their function is to tightly wrap the object when it passes through the through hole 35, filling the gap between the object and the through hole 35, so as to ensure that even if the object passes through, the sealing performance of the shielding cloth 31 is still not affected, effectively preventing dust, water vapor and other impurities from entering the inside of the secondary support frame 12 through the through hole 35, and continuing to provide reliable protection for the coal mine mechanical and electrical equipment.

[0028] In the embodiment of the utility model, the bottom sides of the secondary support frame 12 are both installed with the moving wheel 4, and the sides of the secondary support frame 12 away from the main support frame 1 are both installed with the fixed plate 41, and the fixed plate 41 is slidably connected with the fixed anchor rod 42.

[0029] It should be noted that: the two sides of the bottom of the auxiliary support frame 12 are installed with the moving wheels 4, which improves the mobility of the whole isolation shield, and the side away from the main support frame 1 of the auxiliary support frame 12 is installed with the fixed plate 41, and the fixed plate 41 is provided with the hole for the fixed anchor rod 42 to slide, which is used for fixing the two auxiliary support frames. Through the moving wheels installed on the two sides of the bottom of the auxiliary support frame, the isolation shield can easily move in the complex terrain of the coal mine underground, and the isolation shield can be conveniently and quickly shifted to the electromechanical equipment at different positions for protection. The design of the fixed plate and the fixed anchor rod can firmly fix the isolation shield on the ground after the isolation shield is moved to the specified position, so that the isolation shield is prevented from being shifted due to vibration, external force collision and other factors during the operation of the equipment, and the stability and reliability of the protection are ensured.

[0030] The above only describes the embodiments of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation obtained by using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
