Description

Technical Field

[0001] The utility model relates to the technical field of downhole operation for oil and gas production, and specifically relates to a safety monitoring and warning device for downhole operation of oil and gas production. Background Technique

[0002] The safety monitoring and warning device for downhole operation of oil and gas production is a crucial part in the process of oil and gas exploitation. It can monitor the downhole temperature in real time to prevent equipment damage or fire caused by high temperature.

[0003] In the existing technology, the angle of the device is fixed after installation, resulting in a fixed orientation of the speaker in the audible and visual alarm. When alarming, the intensity of the sound signals received in different directions relative to the audible and visual alarm is different, and the light beam during the flashing of the flash lamp is single, all of which lead to the problem of unsatisfactory warning effect. For this reason, we propose a safety monitoring and warning device for downhole operation of oil and gas production. Content of the Utility Model

[0004] The purpose of the utility model is to provide a safety monitoring and warning device for downhole operation of oil and gas production to solve the problems raised in the above background technique.

[0006] A speaker is arranged on the top of the mounting plate, and a lamp holder is arranged on the top of the speaker. A lamp cover and a flash lamp are arranged on the lamp holder, and the flash lamp is located inside the lamp cover;

[0007] The top of the lamp cover is connected with a rotating shaft through a bearing, and a circular plate is arranged on the top of the rotating shaft. Strip-shaped holes are evenly and circumferentially formed on the circular plate.

[0008] As a preferred scheme of the safety monitoring and warning device for downhole operation of oil and gas production of the utility model, wherein: Bells are evenly and circumferentially arranged on the outer wall of the circular plate.

The driving gear is arranged on a mounting shaft, and the mounting shaft is connected with the output shaft of a reduction motor.

[0011] As a preferred solution of an oil and gas production downhole operation safety monitoring and warning device described in the present utility model, wherein: the reduction motor drives the mounting shaft to rotate in a positive and negative alternating direction.

[0013] As a preferred solution of an oil and gas production downhole operation safety monitoring and warning device described in the present utility model, wherein: an installation cavity for installing the reduction motor is provided inside the lamp holder.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By driving the rotating shaft to rotate through the driving component, the circular plate rotates in a positive and negative alternating manner above the lamp cover, and then the strip-shaped holes rotate back and forth accordingly. In this way, the flash lamp can emit light beams at different positions upward through the lamp cover due to the strip-shaped holes that change positions back and forth. Compared with only the flash lamp flashing, the warning effect is improved;

[0016] 2.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] As mentioned in the background art, regarding the problem of unsatisfactory early warning effect in the prior art.

[0022] The utility model provides a safety monitoring and early warning device for downhole oil and gas production operations.

[0023] Embodiment 1

[0024] Referring to Figures 1 to 2 , a safety monitoring and early warning device for downhole oil and gas production operations includes a mounting plate 1, on which a temperature sensor 2 and a controller 3 are arranged. The mounting plate 1 is mounted on downhole equipment, and the temperature sensor 2 is used to detect the temperature of the equipment;

[0025] A loudspeaker 4 is arranged at the top of the mounting plate 1, and a lamp holder 5 is arranged at the top of the loudspeaker 4. A lamp shade 6 and a flash lamp 7 are arranged on the lamp holder 5, and the flash lamp 7 is located inside the lamp shade 6. The temperature signal is transmitted to the controller 3 for analysis and processing. When the dangerous value is reached, the controller 3 controls the loudspeaker 4 and the flash lamp 7 to work to give an early warning;

[0026] The top of the lamp shade 6 is connected with a rotating shaft 8 through a bearing, and a circular plate 9 is arranged at the top of the rotating shaft 8. Strip-shaped holes 10 are evenly circumferentially formed in the circular plate 9.

[0027] Bells 11 are evenly circumferentially arranged on the outer wall of the circular plate 9.

[0028] The rotating shaft 8 is connected with a driving component. The driving component drives the rotating shaft to rotate, so that the circular plate 9 rotates forward and backward alternately above the lamp shade 6. Then the strip-shaped holes 10 rotate back and forth accordingly. In this way, the flash lamp 7 can emit light beams at different positions upward through the lamp shade 6 due to the strip-shaped holes 10 that change positions back and forth. Compared with only the flash lamp 7 flashing, the early warning effect is improved.

[0029] When the circular plate 9 rotates forward and backward alternately, the surrounding bells 11 rotate back and forth accordingly, and then can shake back and forth to make sounds, so that the sound does not propagate in a fixed direction, thereby further improving the early warning effect. Thus, the early warning effects of both sound and light beams can be improved simultaneously, and the practicability is strong.

[0030] The driving component includes a driven gear 12 arranged on the rotating shaft 8. The right end of the driven gear 12 is meshed and connected with a driving gear 13. The driving gear 13 is arranged on a mounting shaft 14. The mounting shaft 14 is connected with the output shaft of a reduction motor 16. Among them, the reduction motor 16 drives the mounting shaft 14 to rotate in forward and backward alternating directions. The reduction motor 16 is powered by the prior art and is controlled by the controller 3. The mounting shaft 14 drives the driving gear 13 to rotate back and forth, so that the driven gear 12 drives the rotating shaft 8 to rotate back and forth.

[0031] The mounting shaft 14 is connected to both the lamp shade 6 and the lamp base 5 through bearings, improving the stability during rotation.

[0032] Embodiment 2

[0033] Refer to Figures 1 to 2 , an installation cavity 15 for installing the reduction motor 16 is provided in the lamp base 5, for installing the reduction motor 16. The installation cavity 15 can communicate with the outside through a dust-proof net (not shown in the figure), which is used for the heat dissipation of the reduction motor 16.

[0034] All other structures are the same as those in Embodiment 1.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
