[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 4The present invention relates to a safety protection device for well control pressure testing, comprising a support plate 1 and a protection component, the protection component comprising a top guard plate 8 and a plurality of side guard plates 9 located on both sides of the top guard plate 8, two slide grooves 2 are provided on both sides of the support plate 1, and the inside of the slide grooves 2 are slidably connected with a support component 3, two vertical plates 4 are fixedly connected to the two sides of the upper surface of the support plate 1, two cross bars 5 are fixedly connected between the two vertical plates 4, two sliding sleeves 6 are slidably connected to the surfaces of both ends of the two cross bars 5, and the two sliding sleeves 6 are respectively fixedly connected to the two vertical plates 4 with a first spring 20, the two sliding sleeves 6 are rotatably connected to the tops of the two sliding sleeves 6, the tops of the two sliding sleeves 6 are rotatably connected to the lower surface of the top guard plate 8, the middle part of the lower surface of the top guard plate 8 and the upper surface of the support plate 1 are jointly connected with a guide component, slots 10 are provided on both sides of the top guard plate 8 and one end of the plurality of side guard plates 9, and a plug plate 11 that can be inserted into the slot 10 is fixedly connected to the side of the plurality of side guard plates 9 away from the slot 10, a positioning hole 12 is provided in the middle of the plug plate 11, and a clamping component for fixing the plug plate 11 is provided at the bottom of the slot 10.

[0024] like Figure 1-Figure 2 As shown, the support assembly 3 includes a slide rod 31 located inside the slide groove 2, and the slide rod 31 is a square rod. One end of the slide rod 31 located in the slide groove 2 is fixedly connected to a slider 32, and the slider 32 is slidably connected to the inner wall of the slide groove 2. One end of the slide rod 31 located outside the slide groove 2 is fixedly connected to a support rod 33, and the bottom end of the support rod 33 is fixedly connected to a bottom plate 34. A square hole smaller than the slider 32 is opened at one end of the slide groove 2 close to the side of the support plate 1, and the slide rod 31 is slidably connected to the square hole.

[0025] Therefore, when installing the device, the slide rod 31 can be pulled to slide in the slide groove 2 according to the width of the pressure test pit, so as to adjust the distance between the support components 3 on both sides of the support plate 1, so that the support components 3 can be arranged across the top of the pressure test pit, and by setting a slider 32 larger than the square hole, the slide rod 31 can be prevented from detaching from the slide groove 2.

[0026] like Figure 1 As shown, a locking bolt 21 penetrates through the bottom wall of the slide groove 2 near the square hole and is threadedly connected.

[0027] After the position of the sliding rod 31 is adjusted, the locking bolt 21 can be tightened to squeeze the sliding rod 31 to fix the sliding rod 31 .

[0028] like Figure 1-Figure 2 As shown, the guide assembly includes a guide rod 18 fixed to the upper surface of the support plate 1, and a guide tube 19 is slidably connected to the top surface of the guide rod 18, and the top end of the guide tube 19 is fixedly connected to the lower surface of the top guard plate 8.

[0029] The guide tube 19 can slide up and down along the guide rod 18, so that the top guard plate 8 can only move up and down along the direction of the guide rod 18. When the top guard plate 8 is hit, it can only move vertically downward, so that the top guard plate 8 squeezes the inclined rod 7, and then the inclined rod 7 squeezes the sliding sleeve 6 and the first spring 20, converting the downward impact force into a lateral force, and the first spring 20 is used for buffering, so as to protect the internal equipment of the pressure test pit.

[0030] like Figure 1 and Figure 4 As shown, the snap-on assembly includes a through hole 13 opened on the bottom wall of the slot 10, a snap-on rod 14 passes through the through hole 13 and is slidably connected, an end of the snap-on rod 14 located outside the slot 10 is fixedly connected to an end cap 15, the end cap 15 and the lower surface of the top guard plate 8 or the side guard plate 9 are fixedly connected to a second spring 16, and the end of the snap-on rod 14 located in the slot 10 is snapped into the positioning hole 12 on the plug-in board 11.

[0031] When assembling the side guard plates 9 on both sides of the top guard plate 8, first insert the plug plates 11 on the side guard plates 9 into the slots 10 on both sides of the top guard plate 8, and use the second spring 16 to pull the clamping rod 14 to clamp the positioning hole 12 on the plug plate 11, so that the plug plate 11 can be fixed in the slot 10, thereby realizing the splicing of the side guard plate 9 and the top guard plate 8. Similarly, another side guard plate 9 can also be spliced ​​at the bottom of the side guard plate 9 in the above manner. If the side guard plate 9 is to be disassembled, pull the end cap 15 to disengage the clamping rod 14 from the positioning hole 12, and then the plug plate 11 on the side guard plate 9 can be pulled out from the corresponding slot 10, so that the side guard plate 9 can be disassembled.

[0032] like Figure 1 As shown, both sides of the top guard plate 8 and the side guard plates 9 are all inclined. If an object falls and hits the top guard plate 8 and the side guard plates 9, it can fall along the inclined surface and will not stay on the top guard plate 8 and the side guard plates 9 upper surfaces.

[0033] like Figure 1 As shown, the top wall of the sliding sleeve 6 is provided with a plurality of spherical grooves, and a ball 17 is rotatably connected inside each spherical groove, and the bottom end of the ball 17 is rollingly connected to the upper surface of the cross bar 5. When the bottom end of the inclined rod 7 squeezes the sliding sleeve 6 so that the sliding sleeve 6 slides along the cross bar 5, the ball 17 can reduce the friction force, so that the sliding sleeve 6 slides more smoothly.

[0034] Working principle: When installing the device, first pull the slide bar 31 of each support assembly 3 so that the distance between the support assemblies 3 on both sides of the support plate 1 can just be erected on the top of the pressure test pit, then fix the slide bar 31 with the locking bolts 21, and then fix the bottom plate 34 to the ground with screws. Then install the side guard plates 9 on both sides of the top guard plate 8. After the side guard plates 9 on both sides of the top guard plate 8 are spliced, you can continue to splice the side guard plates 9 at the bottom of the side guard plates 9 until the side guard plates 9 on both sides can completely cover the pressure test pit. During use, if an object falls from above and hits the side guard plate 9 or the top guard plate 8, the top guard plate 8 will descend along the guide rod 18, thereby squeezing the diagonal rod 7, and the bottom end of the diagonal rod 7 will push the sliding sleeve 6 to slide along the cross bar 5, so that the first spring 20 is squeezed, and the vertical impact force is dispersed to both sides, which plays a protective role.
