Description

Technical Field

[0001] This utility model relates to the field of wellhead protection structure technology, and in particular to a foldable temporary wellhead protection device. Background Technology

[0002] Existing temporary wellhead protection devices lack a fixed form and often use construction barriers, iron horses, and other facilities as temporary wellhead protection devices. The disadvantages are: construction barriers, iron horses, and other facilities are not suitable for the shape of the wellhead and cannot serve as a warning. They may pose a safety hazard of people falling because they cannot completely cover the wellhead. In addition, construction barriers and iron horses laid flat on the wellhead lack sufficient strength and stability, which may cause pedestrians to fall and get injured. Furthermore, construction barriers and iron horses are inconvenient to move and have low work efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is that the construction barriers and iron horses currently in use are not compatible with imported ones.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a foldable temporary wellhead protection device, including a fixed platform, a solar flashing light set on the fixed platform, and support legs hinged to the bottom of the fixed platform. The support legs are set at equal angles around the center of the fixed platform, and the number of support legs is not less than three. A flexible cloth bag is connected between adjacent support legs, and reflective warning signs are printed on the flexible cloth bag.

[0005] Preferably, the bottom end of the outrigger is hinged to a foot, which includes a hinge rod and a base plate connected to the end of the hinge rod, with the base plate being perpendicular to the hinge rod.

[0006] Preferably, the movable end of the base plate is provided with a threaded hole, and the bottom of the support leg is provided with a limiting structure, which includes a threaded screw. When the base plate is in contact with the ground, the bottom end of the screw is threadedly connected to the threaded hole.

[0007] Preferably, the limiting structure includes a connecting block fixedly connected to the support leg, and the screw is threadedly connected to the connecting block.

[0008] Preferably, the screw is arranged parallel to the support leg, and when the foot rotates to a state of contact with the support leg, the screw is located between the support leg and the screw.

[0009] Preferably, the support leg is provided with a clamping structure, and the end of the flexible bag is detachably connected to the support leg through the clamping structure.

[0010] Preferably, the clamping structure includes a connecting sleeve fixedly fitted on the support leg, a mounting plate fixedly connected to the connecting sleeve, the mounting plates being arranged in pairs, the flexible bag being clamped in the gap between two adjacent mounting plates, and a clamping screw threadedly connected to the mounting plate.

[0011] Preferably, a clamping piece is fixedly connected to one end of the clamping screw located in the gap between the two mounting plates, and an adapter groove adapted to the clamping piece is provided on the inner side wall of the mounting plate away from the clamping screw, and inclined surfaces are provided at the groove openings on both sides of the adapter groove.

[0012] Preferably, the movable end wall of the clamping piece is provided with crisscrossing friction textures.

[0013] Preferably, a fabric tube is fixedly fitted onto the support leg, and the end of the flexible fabric bag is sewn onto the fabric tube.

[0014] This utility model provides a foldable temporary wellhead protection device, which has the following beneficial effects.

[0015] 1. This utility model utilizes a fixed platform with outriggers arranged at equal angles around its center, with at least three outriggers. It can adapt to various well opening shapes, such as round and square, solving the problem of incompatibility between construction barriers, metal barriers, and well openings. Flexible cloth bags connecting adjacent outriggers can completely cover the well opening, avoiding the safety hazard of personnel falling due to incomplete coverage, and significantly improving the comprehensiveness and reliability of the protection.

[0016] 2. The solar-powered flashing lights on the fixed platform can continuously emit warning signals during the day and night. The reflective warning signs on the flexible cloth bag can be clearly seen under light. The dual warning design effectively reminds passersby to pay attention to the location of the wellhead and reduces the possibility of accidents. Compared with construction barriers and iron horses without warning functions, it significantly improves the safety warning effect.

[0017] 3. The feet at the bottom of the outriggers are attached to the ground through the base plate, increasing the contact area with the ground. In conjunction with the connection between the screw in the limiting structure and the threaded hole in the base plate, the angle of the feet can be fixed, preventing the device from shifting or tipping over due to external impact or pedestrian trampling. This solves the problem of insufficient strength and stability of construction barriers and iron horses, and prevents pedestrians from falling and getting injured. Attached Figure Description

[0024] like Figure 1-4 As shown, this utility model provides a foldable temporary wellhead protection device, including a fixed platform 2, a solar flashing light 1 set on the fixed platform 2, and support legs 4 hinged to the bottom of the fixed platform 2. The support legs 4 are arranged at equal angles around the center of the fixed platform 2, and the number of support legs 4 is not less than three. A flexible cloth bag 5 is connected between adjacent support legs 4, and a reflective warning label 6 is printed on the flexible cloth bag 5.

[0025] A hinge 3 is fixedly installed at the bottom edge of the fixed platform 2, and the support leg 4 is rotatably connected to the bottom of the fixed platform 2 through the hinge 3. When arranging the protective device, the support leg 4 is opened, and the flexible cloth bag 5 between the two support legs 4 limits the opening angle of the support leg 4. After the support leg 4 is fully opened, the flexible cloth bag 5 is in a taut state, and in this state, the protective device can be placed stably on the ground.

[0026] The solar-powered strobe light 1 on top of the fixed platform 2 is powered by a battery inside the fixed platform 2 and continuously emits warning signals during the day and night; the reflective warning sign 6 can reflect light and assist the solar-powered strobe light 1 in warning passers-by at night.

[0027] like Figure 1 and Figure 2 As shown. The bottom end of the support leg 4 is hinged to a foot 7. The foot 7 includes a hinge rod and a base plate connected to the end of the hinge rod, with the base plate perpendicular to the hinge rod. When placing the protective device, rotating the foot 7 allows the base plate to be level, increasing the contact area between the support leg 4 and the ground. Furthermore, adjusting the angle of the foot 7 allows for stable contact between the support leg 4 and the ground under different ground conditions. When storing the protective device, rotating the foot 7 moves it to the inside of the support leg 4 for storage.

[0028] like Figure 1 and Figure 2As shown. The movable end of the base plate is provided with a threaded hole, and the bottom of the support leg 4 is provided with a limiting structure, which includes a threaded screw 9. When the base plate is in contact with the ground, the bottom end of the screw 9 is threadedly connected to the threaded hole. After the base plate is in contact with the ground, by rotating the screw 9, the bottom end of the screw 9 is connected to the threaded hole, thereby fixing the angle of the foot 7 relative to the support leg 4 and locking the foot 7.

[0029] like Figure 1 and Figure 2 As shown, to achieve stable installation of the screw 9, the limiting structure includes a connecting block 8 fixedly connected to the support leg 4, and the screw 9 is threadedly connected to the connecting block 8. By rotating the screw 9, the bottom end of the screw 9 is screwed into the threaded hole on the base plate, thereby locking the foot 7.

[0030] like Figure 2 As shown. The screw 9 is arranged parallel to the support leg 4, and when the foot 7 is rotated to a position where it is in contact with the support leg 4, the screw 9 is located between the support leg 4 and the screw 9. When storing the protective device, first unscrew the screw 9 to move it upward, then rotate the foot 7 to the inside of the support leg 4 and screw the screw 9 in to move it downward, thus restricting the rotation of the support leg 4 through the screw 9.

[0031] like Figure 3 The support leg 4 is equipped with a clamping structure, and the end of the flexible bag 5 is detachably connected to the support leg 4 through the clamping structure. When the protective device is installed, the flexible bag 5 is clamped by the clamping structure, and the opening angle of the support leg 4 is limited by the flexible bag 5; when storing the protective device, the flexible bag 5 is removed by loosening the connection between the flexible bag 5 and the clamping structure.

[0032] like Figure 3 and Figure 4 As shown. The clamping structure includes a connecting sleeve 10 fixedly fitted onto the support leg 4. A mounting plate 11 is fixedly connected to the connecting sleeve 10. The mounting plates 11 are arranged in pairs. The flexible bag 5 is clamped in the gap between two adjacent mounting plates 11. A clamping screw 12 is threaded onto the mounting plate 11. When installing the flexible bag 5, the end of the flexible bag 5 is inserted into the gap between two adjacent mounting plates 11, and then the clamping screw 12 is rotated. The clamping screw 12 presses the flexible bag 5 against the surface of the other mounting plate 11, thus achieving the clamping connection of the flexible bag 5.

[0033] like Figure 4As shown. A clamping piece 13 is fixedly connected to one end of the clamping screw 12 located within the gap between the two mounting plates 11. An adapter groove 14, adapted to the clamping piece 13, is formed on the inner sidewall of the mounting plate 11 away from the clamping screw 12. Inclined surfaces are provided at the openings of the adapter groove 14 on both sides. The clamping piece 13 and the adapter groove 14, along with the inclined surfaces at the openings of the adapter groove 14, enhance the stability of the clamping structure in holding the flexible cloth bag 5.

[0034] As a preferred embodiment of this utility model, the movable end wall of the clamping piece 13 is provided with crisscrossing friction textures. By increasing the friction textures, the frictional force between the clamping piece 13 and the flexible cloth bag 5 is increased, which can prevent the flexible cloth bag 5 from becoming loose between the clamping piece 13 and the flexible cloth bag 5.

[0035] In another embodiment of this utility model, to avoid loss or disordered storage after the flexible cloth bag 5 is removed, a cloth tube is fixedly fitted onto the support leg 4, and the end of the flexible cloth bag 5 is sewn onto the cloth tube. The flexible cloth bag 5 is fixed to the support leg 4 by sewing the cloth tube directly onto the surface of the support leg 4.
