[0020] Example 1

[0021] like Figures 1 to 4 As shown, the wellhead protection device in the embodiment of the first aspect of the present invention includes a box body 10, a lock head 20 is welded on the upper inner wall of the box body 10, an upper cover 50 is hingedly connected to the rear side of the top surface of the box body 10, an electromagnetic push rod mounting bracket 40 is screwedly mounted on the lower surface of the upper cover 50, and an electric control lock 30 matching the electromagnetic push rod mounting bracket 40 is mounted on the lower surface of the upper cover 50;

[0022] In the above embodiment, it should be noted that the electromagnetic push rod mounting frame 40 is screwed with an electromagnetic push rod, and the inner wall of the box body 10 can be installed with some water level gauges and pore water pressure gauges for data collection, so that a 4G signal antenna and a positioning antenna are set to realize data transmission and positioning functions;

[0023] The technical effect achieved by the above embodiment is that when the upper cover 50 is closed, the upper cover 50 can be fixed by the electric lock 30 to prevent others from opening it, thereby greatly improving safety.

[0024] Example 2

[0025] like Figures 1 to 4 When the lock 31 is unlocked, the lock 32 is locked and the lock 32 is in a closed state.

[0026] In the above embodiment, it should be noted that the lock frame 31 and the upper cover 50 are fixedly connected by screws, and the slot 70 is located at the upper end of the electromagnetic push rod after installation;

[0027] The technical effect achieved by the above embodiment is: it can be used in conjunction with the electromagnetic push rod. In the absence of an opening signal, the electromagnetic push rod extends naturally and extends into a pre-set groove 60. The lock shaft 32 is stuck by the electromagnetic push rod and cannot rotate. After receiving the opening signal, the electromagnetic push rod retracts and exits the groove 60, and the handle 33 is turned to open the upper cover 50.

[0028] Example 3

[0029] like Figures 1 to 4 As shown, the wellhead protection device includes all the contents of Example 2. In addition, a bolt 80 threadedly connected to the lock shaft 32 is installed on the front of the lock tongue 39. The bolt 80 is sleeved with a second washer 90 and a spring washer 100. The second washer 90 is located at the rear end of the spring washer 100.

[0030] In the above embodiment, it should be noted that the bolt 80 is an M bolt, and the second washer 90 and the spring washer 100 are both annular structures.

[0031] The technical effect achieved by the above embodiment is that the lock tongue 39 can be firmly fixedly connected to the lock shaft 32.

[0032] Example 4

[0033] like Figures 1 to 4 As shown, the wellhead protection device includes all the contents of Example 3. In addition, the bottom end of the box body 10 is fixedly connected to a connecting plate 110, and the bottom end of the connecting plate 110 is welded with three feet;

[0034] In the above embodiment, it should be noted that the box body 10 and the connecting plate 110 are fixedly connected by a plurality of screws;

[0035] The technical effect achieved by the above embodiment is: the connecting plate 110 with the foot is pre-buried in the cement well platform, the upper end surface of the connecting plate 110 coincides with the upper end surface of the well platform, and after the cement solidifies, the box body 10 is screwed to the connecting plate 110.

[0036] Example 5

[0037] like Figures 1 to 4 As shown, the wellhead protection device includes all the contents of Example 4. In addition, the upper cover 50 is hollow and a battery compartment with a lithium battery is installed inside. The back of the upper cover 50 is inlaid with a solar panel 120.

[0038] In the above embodiment, it should be noted that the upper cover 50 is a nylon transmitting cover, which can ensure smooth signal transmission without shielding the signal.

[0039] The technical effect achieved by the above embodiment is: the solar panel 120 can convert light energy into electrical energy and store it in the lithium battery in the battery compartment, and the lithium battery has its own inverter, which can convert direct current into alternating current and power related devices such as the electromagnetic push rod. This part is a universal standard part or a part known to those skilled in the art, and its structure and principle can be known to those skilled in the art through technical manuals or through conventional experimental methods.

[0040] Working principle: Under normal circumstances, the lock tongue 39 and the lock head 20 are staggered and engaged to achieve locking. The electromagnetic push rod naturally extends and penetrates into the groove 60 on the bottom end of the anti-rotation sleeve 37, which can jam the anti-rotation sleeve 37. At this time, the anti-rotation sleeve 37 will not rotate, and the lock shaft 32 and the handle 33 cannot rotate, thereby preventing others from opening the upper cover 50, greatly improving safety. After receiving the opening signal, the electromagnetic push rod retracts and exits the groove 60, and the handle 33 rotates 90° clockwise. At this time, the lock tongue 39 and the lock head 20 are staggered, and the upper cover 50 can be opened, which is convenient to open.
