DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figure 1-7 As shown, an anti-theft hemispherical valve comprises a valve body 1 and a handle 2 installed outside the valve body 1, wherein an anti-theft component for preventing loss is provided outside the bottom end of the valve body 1;

[0032] In order to increase the difficulty of disassembly and prevent theft, Figure 2-7As shown, the anti-theft component includes a mounting seat 3 sleeved on the outside of the two ends of the valve body 1, two mounting plates 4 are installed between the rear ends of the two mounting seats 3, a battery 5 is arranged between the two mounting plates 4, and a solar panel 6 is installed on the top of the mounting plate 4 located on the top of the battery 5. The solar panel 6 absorbs sunlight and converts light energy into electrical energy for storage in the battery 5, thereby improving the service life of the present invention. A plurality of conducting members 7 connected to the battery 5 through wires are installed inside the front end of the mounting plate 4; an electromagnetic ring 8 is arranged inside the front end of each mounting seat 3, the electromagnetic ring 8 is installed inside the valve body 1, and an insulating shell 25 is sleeved on the outside of the electromagnetic ring 8, and the side of the insulating shell 25 close to the positioning ring 9 is sleeved on the outside of a plurality of insulating tubes 11 The electromagnetic ring 8 is shielded and protected by an insulating shell 25 to avoid leakage of electric energy, thereby ensuring the safety of the present invention. The conductive member 7 passes through the valve body 1 and is fixed to the electromagnetic ring 8. A positioning ring 9 is provided on the side of the electromagnetic ring 8 away from the valve body 1, and the end of the positioning ring 9 away from the electromagnetic ring 8 extends to the outside of the valve body 1; wherein, a plurality of spaced active cavities 10 are provided inside the end of the positioning ring 9 close to the electromagnetic ring 8, and an insulating tube 11 is provided inside each active cavity 10, and the end of the insulating tube 11 away from the positioning ring 9 passes through the positioning ring 9 and is fixed to the electromagnetic ring 8, and a spring 12 is provided inside the insulating tube 11, and the two ends of the spring 12 are respectively fixed to the sides close to the positioning ring 9 and the electromagnetic ring 8.

[0033] The staff transmits electric energy to the electromagnetic ring 8 through the conductive member 7, and the electromagnetic ring 8 is energized to drive the springs 12 to attract each other, so that the springs 12 can be contracted to drive the positioning ring 9 to move inward, thereby preventing the positioning ring 9 from protruding and making it inconvenient for the staff to install the valve body 1;

[0034] When the valve body 1 is installed, the electromagnetic ring 8 is powered off, so that the spring 12 can rebound and drive the positioning ring 9 to move outward, so that the positioning ring 9 is inserted into the adjacent pipeline. The valve body 1 can be limited by the positioning ring 9, so that after others disassemble the valve body 1, the positioning ring 9 can still limit and fix the valve body 1 inside, thereby increasing the difficulty of disassembling the valve body 1 and ensuring the safety of the valve body 1.

[0035] In order to enhance the connection stability and use safety of the valve body 1 and the adjacent pipeline, Figure 1-3As shown, both ends of the valve body 1 are sleeved with fixing rings 13, and the front and rear sides of the fixing ring 13 are rotatably connected with connecting brackets 14, and the end of the connecting bracket 14 away from the fixing ring 13 is installed with a clamp 15, and the two corresponding front and rear clamps 15 are fixed together by bolts, and a fixing plate 16 is installed on the top of the fixing ring 13, and an infrared sensor 17 is installed on the side of the top of the fixing plate 16 away from the valve body 1, and a reflector 18 is provided on the side of the infrared sensor 17 away from the fixing plate 16, and the reflector 18 is installed on the top of one of the clamps 15; two alarms 19 are provided between the reflector 18 and the infrared sensor 17, and the two alarms 19 are respectively installed on the side away from the two connecting brackets 14.

[0036] The staff rotates the connection bracket 14 to put the clamp 15 on the adjacent pipeline and fix it with bolts, so as to enhance the connection stability between the valve body 1 and the adjacent pipeline, and also make the reflector 18 correspond to the infrared sensor 17;

[0037] Therefore, when someone else removes the clamp 15, the reflector 18 will be dislocated and separated from the infrared sensor 17. At this time, the alarm 19 will issue an early warning to inform the surrounding personnel, and will also provide feedback to the background personnel, informing them that they need to come over for inspection and maintenance in time, thereby improving the safety of the present invention.

[0038] At the same time, in order to prevent others from accidentally operating the handle 2, the handle 2 needs to be shielded and protected, such as Figure 1 and 2 As shown, a threaded rod 20 is provided on the front side of the battery 5, and both ends of the threaded rod 20 are movably connected to the two mounting seats 3 through bearings, and the threads at both ends of the threaded rod 20 are in opposite directions. Both ends of the threaded rod 20 are threadedly connected to a movable plate 21 with an L-shaped cross-section. A sleeve 22 is installed on the front side of the front end of the movable plate 21. The sleeve 22 is sleeved on the outside of one end of the handle 2. A rubber ring 24 is provided between the bottom ends of the two movable plates 21. The rubber ring 24 is sleeved on the outside of the threaded rod 20. Through the connection between the rubber ring 24 and the threaded rod 20, the friction between the hand of the staff and the threaded rod 20 can be enhanced to prevent the threaded rod 20 from loosening.

[0039] By rotating the threaded rod 20 to drive the two movable plates 21 to move inward at the same time, the housing 22 can be mounted on the outside of the handle 2 through the movable plates 21, thereby achieving the effect of shielding and protecting the handle 2 and avoiding the situation where the handle 2 is rotated due to collision or misoperation, thereby ensuring the operational safety of the present invention. At the same time, the threaded rod 20 can be reversed to drive the movable plates 21 to move outward, so that the housing 22 is separated from the handle 2, thereby facilitating the staff to rotate the handle 2.

[0040] In order to ensure the stability of the movable plate 21 during lateral movement, the movable plate 21 needs to be limited. Figure 3 As shown, a positioning column 23 is provided at the bottom of the threaded rod 20, and the two ends of the positioning column 23 are respectively fixed together with two mounting seats 3, and the bottom end of the movable plate 21 is sleeved on the outside of the positioning column 23. By virtue of the connection between the positioning column 23 and the movable plate 21, the positioning column 23 can limit the movable plate 21, thereby ensuring the movement stability of the movable plate 21 and avoiding the displacement of the movable plate 21 during movement.

[0041] In order to ensure the movement stability of the positioning ring 9, it is necessary to limit the movement of the positioning ring 9, such as Figure 4-7 As shown, a limiting ring 26 is sleeved on the outer side of one end of the insulating tube 11 close to the positioning ring 9, and the outer diameter of the limiting ring 26 is equal to the inner diameter of the active cavity 10. By means of the nested connection between the limiting ring 26 and the active cavity 10, the limiting ring 26 can only move inside the active cavity 10, thereby achieving the effect of limiting the positioning ring 9 and preventing the positioning ring 9 from separating from the insulating tube 11.

[0042] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
