The top cover thereof will completely block the air outlet of the fans, so that the fans can only be reduced in size and arranged on the sides, thereby reducing the heat dissipation effect and affecting the shielding function of the shield. Summary of the invention

[0004] In order to overcome the disadvantage that the top cover currently used to store the antenna completely blocks the air outlet of the fan, so that the fan can only be reduced and set on the side, thereby reducing the heat dissipation effect and affecting the shielding function of the shield, the present invention provides a signaling shield.

[0005] The technical solution is: a signaling shield, including a shield, a connector and an antenna; the shield is equidistantly connected to a number of connectors; each connector is respectively connected to an antenna in a damped rotation manner, and each antenna is respectively electrically connected to a connector; it also includes a mounting plate 1, a mounting plate 2, a limit plate and a flexible pad; the shield is fixedly connected to the mounting plate 1; the upper side of the mounting plate 1 is detachably connected to the mounting plate 2; a number of limit plates are respectively equidistantly connected to the mounting plate 1 and the mounting plate 2; the two limit plates in the vertical direction cooperate with each other; each limit plate is respectively fixed to a flexible pad.

[0006] As an improvement of the above solution, a plurality of sliding grooves are provided on both the mounting plate 1 and the mounting plate 2; each limit plate is connected to the mounting plate 1 and the mounting plate 2 in a damping sliding manner via two sliding grooves.

[0007] As an improvement of the above scheme, it also includes a mounting frame; the mounting frame is rotatably connected to the shield; and the lower part of each antenna is connected to the mounting frame.

[0008] As an improvement of the above solution, a plurality of through holes are opened on the mounting frame; each antenna is located in a through hole respectively.

[0009] As an improvement of the above solution, a sponge pad is arranged inside the through hole.

[0010] As an improvement of the above scheme, it also includes a receiving frame, a cleaning plate, a cleaning tube and annular cleaning cotton; a plurality of receiving frames are fixedly connected to the shield; a cleaning plate is placed on all the receiving frames; a plurality of cleaning tubes are connected to the cleaning plate; and an annular cleaning cotton is fixedly connected to each cleaning tube.

[0011] As an improvement of the above scheme, it also includes a polished rod, a third mounting plate, an arc-shaped clamping plate and a double-threaded rod; a plurality of polished rods are fixedly connected to the mounting frame; two mounting plates three are slidably connected to all the polished rods; the two mounting plates three are symmetrically arranged front and back; a plurality of arc-shaped clamping plates are respectively fixedly connected to the opposite sides of the two mounting plates three; a double-threaded rod is rotatably connected to the mounting frame; and the two mounting plates three are both screwed to the double-threaded rod.

[0012] As an improvement to the above solution, the upper side of the arc-shaped clamping plate is arranged in an inclined shape.

[0013] As an improvement of the above scheme, it also includes a gear ring, a sliding plate, a rack and a cleaning strip; each cleaning cylinder is rotatably connected to the cleaning plate; each cleaning cylinder is fixedly connected with a gear ring; the cleaning plate is slidably connected with the sliding plate; a number of racks are fixedly connected with equal distances on the sliding plate; each gear ring is meshed with a rack; a number of cleaning strips are fixedly connected to the upper side of each arc-shaped splint.

[0014] As an improvement of the above solution, it also includes magnetic blocks; a plurality of magnetic blocks are fixedly connected to the cleaning plate.

[0015] The beneficial effects are as follows: 1. The present invention designs the mounting plate, the limit plate and the flexible pad for fixing the end of the antenna to be relatively short and installs them at the end away from the connector. Such a layout not only does not block the wind blown out by the fan in the middle of the shield, but also ensures the maximization of the heat dissipation effect; in addition, a certain gap is retained between the mounting plate and the upper surface of the shield to prevent obstruction to the heat dissipation of the upper surface of the shield, thereby ensuring efficient heat dissipation of the shield for stable operation.

[0016] 2. Before the antenna is bent ninety degrees clockwise around the rotating shaft connected to the corresponding connector, the present invention first slides the limiting plate and the flexible pad corresponding to the short antenna forward in the corresponding sliding groove, so that after the antenna is bent ninety degrees clockwise around the rotating shaft connected to the corresponding connector, the end of the short antenna can also fall on the flexible pad, so that the short antenna will not rotate and protrude at will, thereby avoiding being accidentally touched and pulled, causing damage.

[0017] 3. The present invention puts the cleaning plate on the antenna and pushes it downward. During this process, the annular cleaning cotton will slide on the antenna. Since the annular cleaning cotton has adaptive deformation ability, it can fit tightly on the surface of the antenna. Thus, all dust attached to the antenna can be wiped off during the sliding process. In this way, all dust on the antenna can be cleaned efficiently at one time. During the entire cleaning process, the antenna always remains in a vertical state, thereby ensuring the stability of the signal shielding effect.

[0018] 4. In the present invention, before putting the cleaning plate on the antenna, the worker manually rotates the double-threaded rod. The rotation of the double-threaded rod will drive the two arc-shaped clamping plates and their related components to slide toward each other on the light rod, so that the two front and rear pairs of arc-shaped clamping plates contact each other, clamping the antenna to a vertical state, so that all the annular cleaning cotton can be smoothly put on the antenna.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] A signaling jammer, such as Figure 1-4 As shown, it includes a shield 1, a connector 2 and an antenna 3; the shield 1 is equidistantly connected to six connectors 2; each connector 2 is respectively connected to an antenna 3 in a damped rotation manner, and each antenna 3 is respectively electrically connected to a connector 2;

[0031] It also includes a mounting plate 1 4, a mounting plate 2 8, a limiting plate 5 and a flexible pad 7; a mounting plate 1 4 is fixedly connected to the rear of the shield 1; a mounting plate 2 8 is detachably connected to the upper side of the mounting plate 1 4; six limiting plates 5 are equidistantly connected to the mounting plate 1 4 and the mounting plate 2 8 respectively; the two limiting plates 5 in the vertical direction cooperate with each other; and a flexible pad 7 is fixedly connected to each limiting plate 5.

[0032] Twelve sliding grooves 6 are provided on the mounting plate 1 4 and the mounting plate 2 8 ; each limiting plate 5 is connected to the mounting plate 1 4 and the mounting plate 2 8 in a damping sliding manner via two sliding grooves 6 .

[0033] It also includes a mounting frame 21 ; the front of the shield 1 is rotatably connected to the mounting frame 21 ; and the lower part of each antenna 3 is connected to the mounting frame 21 .

[0034] Six through holes 22 are formed on the mounting frame 21 ; each antenna 3 is located in a through hole 22 , and a sponge pad is provided inside the through hole 22 to prevent the antenna 3 from being damaged.

[0035] When in use, a worker places the present invention at a place where it is to be used, connects the shield 1 to an external power source, makes the antenna 3 in a vertical state, and then controls the shield 1 to work, and transmits the communication blocking signal through the connector 2 and the antenna 3 to interfere with the communication and realize the signal shielding function; when the present invention is to be moved, the power supply is first disconnected, the mounting plate 2 8 and the limit plate 5 and the flexible pad 7 connected thereto are picked up, so that the mounting plate 2 8 is separated from the mounting plate 1 4, so that the limit plate 5 and the flexible pad 7 on the mounting plate 1 4 are exposed, and then, based on the view from right to left, the worker bends all the antennas 3 clockwise by 90 degrees around the rotating shaft connected to the corresponding connector 2 , so that the end of the antenna 3 is against the flexible pad 7, and then the mounting plate 2 8 and the limit plate 5 and the flexible pad 7 connected thereto are mounted back on the mounting plate 1 4. In this way, the end of the antenna 3 is clamped and fixed by the upper and lower flexible pads 7. From the root to the end, the diameter of the antenna 3 generally shows a trend of gradually shrinking, and the flexible pad 7 has excellent shape adaptability and can be flexibly deformed according to the size and shape of the antenna 3 to ensure that the end of the antenna 3 is tightly and stably clamped. Therefore, in the process of transferring the present invention, the antenna 3 can remain stable and is not prone to arbitrary rotation or protrusion, thereby effectively preventing damage caused by accidental touch or breaking;

[0036] In order to ensure that the fan in the middle of the shield 1 can effectively dissipate heat for the internal components, the mounting plate 1 4, the limiting plate 5 and the flexible pad 7 are designed to be relatively short and are installed at the end away from the connector 2. Such a layout will not block the wind blown by the fan in the middle of the shield 1, ensuring the maximum heat dissipation effect; in addition, a certain gap is reserved between the mounting plate and the upper surface of the shield 1 to prevent the heat dissipation of the upper surface of the shield 1 from being hindered, thereby ensuring the efficient heat dissipation of the shield 1 for stable operation;

[0037] In order to transmit different types of signaling, the signaling jammer 1 is usually equipped with antennas 3 of various lengths. Some antennas 3 are very short. After the short antenna 3 is bent ninety degrees clockwise around the rotating shaft connected to the corresponding connector 2, its end will be located in front of the corresponding limiting plate 5 and the flexible pad 7, resulting in the end of the short antenna 3 being unable to be clamped and fixed by the flexible pad 7, which in turn causes the short antenna 3 to rotate and protrude when the present invention is transferred, thereby being accidentally touched and pulled, causing damage; therefore, before the antenna 3 is bent ninety degrees clockwise around the rotating shaft connected to the corresponding connector 2, the limiting plate 5 and the flexible pad 7 corresponding to the short antenna 3 are first slid forward in the corresponding sliding groove 6, so that after the antenna 3 is bent ninety degrees clockwise around the rotating shaft connected to the corresponding connector 2, the end of the short antenna 3 can also fall on the flexible pad 7, so that the short antenna 3 will not rotate and protrude at will, thereby avoiding being accidentally touched and pulled, causing damage;

[0038] When workers rotate all the antennas 3 around the rotating shafts connected to the corresponding connectors 2, they need to operate the antennas 3 one by one, which is cumbersome and time-consuming. Therefore, a mounting bracket 21 is provided to connect with all the antennas 3. When the antenna 3 needs to be rotated, the worker can rotate the mounting bracket 21, and the mounting bracket 21 will drive all the antennas 3 to rotate at the same time. The operation is simple and quick. In order to avoid affecting the heat dissipation of the antenna 3, six through holes 22 are opened on the mounting bracket 21. When the antenna 3 is in a vertical working state, each antenna 3 is located in a through hole 22, so as to prevent the mounting bracket 21 from contacting the antenna 3 and affecting the heat dissipation of the antenna 3. A sponge pad is provided on the inner side of the through hole 22 to prevent damage to the antenna 3.

[0039] Example 2

[0040] On the basis of Example 1, Figure 4-7 As shown, it also includes a receiving frame 23, a cleaning plate 24, a cleaning tube 25 and an annular cleaning cotton 26; two receiving frames 23 are fixedly connected to the front side of the shield 1; a cleaning plate 24 is placed on all the receiving frames 23; six cleaning tubes 25 are connected to the cleaning plate 24; and an annular cleaning cotton 26 is fixedly connected to each cleaning tube 25.

[0041] It also includes a light rod 31, a mounting plate three 32, an arc-shaped clamping plate 33 and a double-threaded rod 34; two light rods 31 are fixedly connected to the mounting frame 21; two mounting plates three 32 are slidably connected to all the light rods 31; the two mounting plates three 32 are symmetrically arranged front and back; six arc-shaped clamping plates 33 are fixedly connected to the opposite sides of the two mounting plates three 32, and the upper sides of the arc-shaped clamping plates 33 are arranged in an inclined shape to guide the cleaned dust outward; a double-threaded rod 34 is rotatably connected to the mounting frame 21; the two mounting plates three 32 are both screwed to the double-threaded rod 34.

[0042] In order to ensure the safety and stability of mining operations, the signal shielding device 1 is also used in dusty environments such as mining. When used in such an environment, a large amount of dust is easily attached to the surface of the antenna 3, and the dust will change its electromagnetic characteristics, causing interference with the transmission of the signal. This interference may cause the signal strength to weaken, thereby affecting the working range and effect of the shielding device 1; therefore, workers are required to regularly clean the dust on the surface of the antenna 3. When cleaning, workers are required to wipe and clean the antennas 3 one by one. The antennas 3 are generally arranged very closely, so when wiping, workers need to rotate the antennas 3 one by one to a slightly tilted and protruding state in order to wipe the dust off the surface of the antenna 3. When the antenna 3 is tilted, its signal strength in the target area will be weakened, reducing the shielding effect; when it is necessary to clean the dust on the antenna 3, the worker lifts the cleaning plate 24 and its associated components and places them above the antenna 3, so that the annular cleaning cotton 26 is aligned with the antenna 3, such as Figure 7As shown, the cleaning plate 24 is then put on the antenna 3 and pushed downward. During this process, the annular cleaning cotton 26 will slide on the antenna 3. Since the annular cleaning cotton 26 has adaptive deformation ability, it can fit the surface of the antenna 3 tightly, so that all dust attached to the antenna 3 can be wiped off during the sliding process. In this way, all dust on the antenna 3 can be cleaned up at one time and efficiently. During the entire cleaning process, the antenna 3 always remains in a vertical state, thereby ensuring the stability of the signal shielding effect; after cleaning, the cleaning plate 24, the cleaning cylinder 25 and the annular cleaning cotton 26 are pulled out upward and put back into the receiving frame 23;

[0043] After the shield 1, the connector 2 and the antenna 3 have been used for a long time, the rotating parts may become loose, causing part of the antenna 3 to deviate, or the worker may accidentally touch the antenna 3, which may also cause the antenna 3 to deviate. At this time, the annular cleaning cotton 26 cannot be smoothly put on the antenna 3; therefore, before putting the cleaning plate 24 on the antenna 3, the worker manually rotates the double-threaded rod 34, and the rotation of the double-threaded rod 34 will drive the two arc-shaped clamping plates 33 and their related parts to slide toward each other on the light rod 31, so that the two front and rear pairs of arc-shaped clamping plates 33 contact each other, clamping and restricting the antenna 3 to a vertical state, so that all the annular cleaning cotton 26 can be smoothly put on the antenna 3;

[0044] In addition, the upper side of the arc-shaped clamping plate 33 is arranged to be inclined so as to guide the cleaned dust outwards and prevent the cleaned dust from falling on the rotating shaft connecting the connector 2 and the antenna 3 to affect the rotation of the connector 2 .

[0045] Example 3

[0046] On the basis of Example 2, Figure 6-8 As shown, it also includes a gear ring 35, a sliding plate 36, a rack 37 and a cleaning strip 38; each cleaning cylinder 25 is rotatably connected to the cleaning plate 24; each cleaning cylinder 25 is respectively fixed with a gear ring 35; the cleaning plate 24 is slidably connected with a sliding plate 36; six racks 37 are equidistantly fixed to the lower side of the sliding plate 36; each gear ring 35 is respectively meshed with a rack 37; and five cleaning strips 38 are respectively fixed to the upper side of each arc-shaped clamping plate 33.

[0047] It also includes a magnetic block 39; two magnetic blocks 39 are fixedly connected to the rear side of the cleaning plate 24.

[0048] After the annular cleaning cotton 26 wipes off the dust on the antenna 3, some of the dust will adhere to the lower part of the annular cleaning cotton 26. In the process of pulling the cleaning plate 24, the cleaning cylinder 25 and the annular cleaning cotton 26 upward, the annular cleaning cotton 26 will re-attach some of the dust to the antenna 3, affecting the shielding effect; after the annular cleaning cotton 26 wipes off the dust on the antenna 3, the magnetic block 39 is in contact with the mounting frame 21 for adsorption and fixation. At this time, the lower part of the annular cleaning cotton 26 is attached to the upper side of the arc-shaped clamping plate 33, and the lower part of the annular cleaning cotton 26 is in contact with the cleaning strip 38, and then, the worker The person pulls the sliding plate 36 back and forth, and the sliding plate 36 slides back and forth in the cleaning plate 24. The sliding plate 36 drives the rack 37 to move back and forth, and the rack 37 drives the gear ring 35 to rotate back and forth, so that the gear ring 35, the cleaning tube 25 and the annular cleaning cotton 26 rotate back and forth. When the annular cleaning cotton 26 rotates back and forth, the dust attached to the lower part of the annular cleaning cotton 26 will be removed by the cleaning strip 38. In this way, it is avoided that in the process of pulling the cleaning plate 24, the cleaning tube 25 and the annular cleaning cotton 26 upward, the annular cleaning cotton 26 will not re-attach part of the dust to the antenna 3, thereby affecting the shielding effect.
