Description

Technical Field

[0001] The utility model relates to the technical field of bridge type water distributors, in particular to a bridge type water distributor. Background Technique

[0002] The bridge type water distributor is a special downhole tool for quantitatively injecting water into each oil layer during layered water injection, and mainly consists of a water distribution main body, a water distribution nozzle, a nozzle body, a gland and a sealing ring.

[0003] For example, a bridge type concentric water distributor with the publication number of "CN113279736A". In this bridge type concentric water distributor, by setting a connected bridge type channel, a water passing hole, a water passing channel and a fixed water hole, and driving the concentric adjusting sleeve to rotate by a strong magnetic drive ring and cooperating with a compression spring, the adjusting water passing sleeve is driven to move up and down, so as to adjust the flow area of the fixed water hole and the water guiding hole outside the adjusting water passing sleeve, thereby realizing the adjustment of the water output. The structure is relatively simple and the construction difficulty is reduced. However, in the use of the water distributor, in order to realize bridging, a packer needs to be docked. The connection between the water distributor and the packer is installed by inserting and then fixed by tightening with bolts. This is fixed by the friction between objects, which causes wear to the water distributor and the packer itself, affects the long-term connection stability, affects the normal use of the water distributor, and shortens the service life of the water distributor. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of affecting the normal use of the water distributor and shortening the service life of the water distributor, and to propose a bridge type water distributor.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] Design a bridge type water distributor, including a sleeve and a thread. The outer wall of the sleeve is processed with a thread. Water distributors are fixedly connected to the inner walls of both sleeves. The upper and lower sides of the water distributor are respectively communicated with straight pipes. Fixed structures are respectively connected to the left and right sides of both straight pipes. A protective structure is connected to the outer wall of the thread.

[0007] Preferably, the fixed structure includes a bracket and a vertical plate. The inner sides of multiple brackets are respectively fixedly connected to the left and right sides of the straight pipe. The inner wall of the bracket is rotationally connected to the outer wall of the vertical plate. A curved plate is fixedly connected to the inner end of the vertical plate. A spring is fixedly connected to the inner side of the vertical plate.

[0008] Preferably, the inner side of the spring is fixedly connected to the outer wall of the straight pipe.

[0009] Preferably, a packer is inserted into the outer wall of the straight pipe located above.

[0010] Preferably, the notches on the left and right sides of the packer are respectively inserted into the inner sides of the outer walls of the curved plates.

[0011] Preferably, the protection structure includes a cylinder and a circular opening. The inner wall of the cylinder is threadedly connected to the outer wall of the thread. The front surface of the cylinder is machined with a circular opening, and a straight rod is inserted into the inner wall of the circular opening.

[0012] The beneficial effects of a bridge-type water distributor proposed by the present utility model are as follows: In the fixing structure, the vertical plate rotates outward through the pin shaft on the inner wall of the bracket. At this time, the vertical plate drives the curved plate to move outward, and at the same time, the vertical plate stretches the spring. Then, the connecting contact of the packer is inserted into the outer wall of the straight pipe. Subsequently, the vertical plate is released, and the spring loses the stretching force and provides a resilience force, causing the vertical plate to drive the curved plate to rotate inward, so that the curved plate is inserted into the notch on the outer wall of the packer, completing the installation of the packer and the water distributor. Changing the original installation form improves the stability, ensures the normal use of the water distributor, and guarantees the service life of the water distributor.

[0018] The present utility model will be further described below with reference to the accompanying drawings:

[0019] Embodiment 1:

[0020] Please refer to Figures 1-4: In this embodiment, a bridge - type water distributor includes a sleeve 1 and a thread 4. The outer wall of the sleeve 1 is processed with the thread 4. Water distributors 5 are fixedly connected to the inner walls of both sleeves 1. How to operate and use the water distributor 5 is already prior art and will not be elaborated in detail. The model is selected according to the usage requirements. The water distributor 5 is a bridge - type water distributor. The upper and lower sides of the water distributor 5 are respectively communicated with straight pipes 6. Fixed structures 2 are respectively connected to the left and right sides of the two straight pipes 6. A protective structure 3 is connected to the outer wall of the thread 4.

[0021] The fixed structure 2 includes a bracket 201 and a vertical plate 202. The inner sides of multiple brackets 201 are respectively fixedly connected to the left and right sides of the straight pipe 6. The inner wall of the bracket 201 is rotationally connected to the outer wall of the vertical plate 202. The vertical plate 202 rotates through a pin shaft on the inner wall of the bracket 201 under force. A curved plate 203 is fixedly connected to the inner end of the vertical plate 202. A spring 204 is fixedly connected to the inner side of the vertical plate 202. The inner side of the spring 204 is fixedly connected to the outer wall of the straight pipe 6. After the vertical plate 202 is forced to rotate outward, it rebounds through the elastic force of the spring 204.

[0022] By making the vertical plate 202 rotate outward through the pin shaft on the inner wall of the bracket 201 in the fixed structure 2, at this time, the vertical plate 202 drives the curved plate 203 to move outward. At the same time, the vertical plate 202 stretches the spring 204. Then, the connecting contact of the packer 7 is inserted into the outer wall of the straight pipe 6. Subsequently, the vertical plate 202 is released. The spring 204 loses the stretching force and provides a resilience force, causing the vertical plate 202 to drive the curved plate 203 to rotate inward, so that the curved plate 203 is inserted into the notch on the outer wall of the packer 7, completing the installation of the packer 7 and the water distributor 5. Changing the original installation form improves the stability, ensures the normal use of the water distributor, and guarantees the service life of the water distributor.

[0023] A packer 7 is inserted into the outer wall of the upper straight pipe 6. The model of the packer 7 is selected according to the usage requirements. The left and right notches of the packer 7 are respectively inserted into the inner sides of the outer walls of the curved plates 203. The protective structure 3 includes a cylinder 301 and a round opening 302. The inner wall of the cylinder 301 is threadedly connected to the outer wall of the thread 4. The cylinder 301 rotates up and down through the outer wall of the thread 4 under force. A round opening 302 is processed on the front surface of the cylinder 301. A straight rod 303 is inserted into the inner wall of the round opening 302. The straight rod 303 cooperates with the round opening 302 to facilitate driving the cylinder 301 to rotate.

[0024] Working principle:

[0025] Installation of the bridge - type water distributor:

[0026] Rotate the vertical plate 202 outward through the pin shaft on the inner wall of the bracket 201. At this time, the vertical plate 202 drives the curved plate 203 to move outward. At the same time, the vertical plate 202 stretches the spring 204. Then insert the connecting contact of the packer 7 into the outer wall of the straight pipe 6. Subsequently, release the vertical plate 202. The spring 204 loses the tensile force and provides a resilience force, causing the vertical plate 202 to drive the curved plate 203 to rotate inward, so that the curved plate 203 is inserted into the notch on the outer wall of the packer 7, completing the installation of the packer 7 and the water distributor 5. When multiple packers 7 and water distributors 5 are docked, a bridge will be formed, which is called a bridge-type water distributor.

[0027] Protection of the bridge-type water distributor:

[0028] After the packer 7 and the water distributor 5 are docked, insert the rear outer wall of the straight rod 303 into the inner wall of the round opening 302. Then hold the straight rod 303 and push it in one direction, causing the straight rod 303 to drive the cylinder 301 to rotate through the thread 4, so that the cylinder 301 gradually approaches the fixed structure 2 until the inner wall of the cylinder 301 covers the outer walls of the bracket 201 and the vertical plate 202 inside, which can prevent the vertical plate 202 from rotating outward under force.

[0029] Embodiment 2:

[0030] Please refer to Figures 1-4 : In this embodiment, a bridge-type water distributor further includes a ring 8, and the outer wall of the ring 8 is fixedly connected to the inner wall of the cylinder 301.

[0031] Working principle:

[0032] After the vertical plate 202 rotates outward under force, it will come into contact with the ring 8. The ring 8, due to its rubber material, can prevent the vertical plate 202 from directly colliding and being damaged with the cylinder 301, and at the same time avoid generating impact sounds.

[0033] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
