[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0022] The utility model provides a wellhead anti-falling device, such as Figure 1-4 As shown, it includes a fixed support 1 and a movable cover plate 2. The fixed support 1 is pre-buried 50 cm below the wellhead. A mounting groove 11 for mounting the movable cover plate 2 is provided on the top surface of the fixed support 1. A circular hole 12 is provided at one end of the mounting groove 11. The circular hole 12 runs through the upper and lower surfaces of the fixed support 1. The movable cover plate 2 is a square structure, and a plurality of leakage holes are provided in the middle thereof. Guide members 8 are provided on both sides of the interior of the mounting groove 11. The movable cover plate 2 is placed on the top surface of the guide member 8 and is slidably connected to the guide member 8. A handle 3 is fixedly connected to one end of the top surface of the movable cover plate 2. The handle 3 is used to push and pull the movable cover plate 5. At the same time, when the movable cover plate 5 is opened, the movable cover plate 5 is slid into one end of the mounting groove 11. The handle 3 is used to block the mounting plate 3 to prevent the movable cover plate 5 from completely sliding into the fixed support 1, which makes it inconvenient to take out the movable cover plate 5 to close the wellhead.
[0023] By slidingly installing the movable cover plate 2 in the fixed support 1, the sliding and retracted placement of the movable cover plate 2 is achieved, and the fixed support 1 is pre-buried 0-50cm below the wellhead, so that the movable cover plate 2 can provide secondary shielding for the wellhead to catch people who fall into the wellhead, thereby achieving a dual protection function, preventing people who fall into the wellhead from falling to the bottom of the wellhead, facilitating self-rescue or rescue work, and greatly improving the safety of the wellhead facilities. It is suitable for the deployment and implementation of wells with inspection ports such as rainwater wells, sewage wells, and septic tanks.
[0024] The movable cover plate 2 can be slidably placed in the fixed support 1 to realize the invisible design of the movable cover plate 2. When inspecting the wellhead, the movable cover plate 2 can be pushed into the other end of the installation groove 11 opened in the fixed support 1, so that the maintenance personnel can smoothly enter the wellhead;
[0025] At the same time, the movable cover plate 5 is placed in the installation groove 11 provided in the fixed support 1 through the guide member 8, which can greatly reduce the friction between the movable cover plate 2 and the fixed support 1, making it easier to push the movable cover plate 2.
[0026] As one of the embodiments, Figure 2 , 3As shown, the guide member 8 includes a guide rail 81 and a roller 82. The guide rail 81 is fixedly installed on both sides of the circular hole 12. A plurality of rollers 82 are equidistantly rotatably installed inside the guide rail 81, and the top surfaces of the rollers 82 protrude from the guide rail 81. The bottom surface of the movable cover 2 contacts with the plurality of rollers 82, thereby realizing a rolling connection between the movable cover 2 and the rollers 82, and facilitating the pushing of the movable cover 2.
[0027] Specifically, Figure 4 As shown, a baffle 6 is detachably installed on the top surface of the circular hole 12, and the baffle 6 is provided with a circular hole corresponding to the circular hole 12 and having the same size. Under the action of the baffle 6, the edge position of the movable cover 2 can be limited and fixed to prevent the movable cover 2 from shaking due to the impact of rainwater pipe water overflowing upward, thereby improving the protection of the password lock 5 and the stability of the closed state of the movable cover 2.
[0028] As one of the embodiments, Figure 1 , 3 As shown, an arc seat 4 is welded to the end of the top surface of the fixed support 1 away from the circular hole 12, and a password lock 5 is arranged in the middle of the front end of the arc seat 4. A lock hole is opened at the end of the movable cover 2 away from the handle 3, and the lock hole is adapted to the latch of the password lock 5. The end of the fixed support 1 with the arc seat 4 is pre-buried 0-50cm below the bottom surface. Under the action of the arc seat 4, when the soil presses down the fixed support 1, the force on the surface of the fixed support 1 is more uniform, thereby improving the strength of the fixed support 1. At the same time, a password lock 5 is added to lock the movable cover 2, which can not only effectively prevent the movable cover 2 from sliding and displacing, and improve the stability of the movable cover 2 when it is closed, but also prevent non-staff from opening the movable cover 2, avoid the theft of the movable cover 2, and prevent the hidden dangers of non-staff going down the well.
[0029] Specifically, the movable cover plate 2 is made of flame-retardant and anti-corrosion glass fiber reinforced plastic material, and the fixed support 1 and the arc-shaped seat 4 are made of cement concrete.
[0030] The working principle of the utility model is as follows: the fixed support 1 is pre-buried at 0-50cm below the wellhead, and in the initial state, the movable cover plate 2 completely covers the circular hole 12 opened in the fixed support 1, so that the movable cover plate 2 performs secondary shielding on the wellhead, and is used to receive people who fall into the wellhead, thereby realizing a dual protection function, preventing people who fall into the wellhead from falling to the bottom of the wellhead, facilitating self-rescue or rescue work, and greatly improving the safety of the wellhead facilities; when opening, first open the combination lock 5 and then use the handle 3 to push and pull the movable cover plate 2 until the handle 3 is pulled and moves to abut against the front of the arc seat 4.
