Description

Technical Field

[0001] This utility model relates to the field of safety detection technology, and in particular to a safety verification device for power production sites. Background Technology

[0002] With urban construction and economic development, the scale and quantity of electricity production are increasing year by year; thus, the power production sector has a large amount of on-site work. Power companies' transmission, distribution, and substation specialties complete the construction, maintenance, and operation of power facilities such as transmission lines, distribution lines, and substations. Faced with a large number of on-site production operations, power companies adopt multiple safety mechanisms, such as work permits, safety responsibilities, and safety procedures, to ensure the safety of on-site power production work, improve the safety awareness of production workers, and avoid personnel injuries and equipment failures.

[0003] A search revealed that patent document CN215182062U discloses a safety verification device for power production sites, comprising a housing, an upper gear fixedly connected inside the housing, a lower gear meshing with the upper gear, a rotating shaft fixedly connected to the lower gear, a gear fixedly connected to the rotating shaft, a rotating gear meshing with the gear, a retrieval rod fixedly connected to the rotating gear, a pull rope rotatably connected to the retrieval rod, a pulley connected to the pull rope, a slider fixedly connected to the pull rope, an identifier fixedly connected to the slider, a sliding groove slidably connected to the slider, a slot fixedly connected inside the housing, an electric plate fixedly connected to the slot, an electric plate I fixedly connected to the slot, a shifting groove fixedly connected to the slot, a sensing block slidably connected to the shifting groove, and a spring fixedly connected to the sensing block.

[0004] However, the aforementioned patents suffer from safety issues because workers wearing sweaters in cold weather are prone to static electricity, and the lack of static electricity removal functionality during employee detection and identification poses a significant risk of fire caused by electrical disturbances in the production area. Therefore, we propose a safety verification device for power production sites to address these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a safety verification device for power production sites. It aims to solve the problem that when workers wear sweaters in cold weather, they are prone to static electricity. However, there is no function to remove static electricity when detecting and identifying employees, which may lead to fires caused by electricity in the production site and result in low safety. Therefore, this power production site safety verification device is proposed.

[0006] This utility model is achieved through the following technical solution:

[0007] The power production site safety verification device includes:

[0008] case;

[0009] There are two partitions, which are symmetrically fixedly installed inside the housing, and an identifier is slidably connected between the two partitions.

[0010] The lifting mechanism, located inside the housing, is used to lift the identifier.

[0011] A recessed seat is fixedly installed at the bottom of the identifier. A motor is fixedly installed inside the identifier. Supports are fixedly installed on both inner walls of the recessed seat. A second motor is installed inside the housing.

[0012] The static elimination mechanism, located on a recessed base, is used to eliminate static electricity for employees undergoing identity verification.

[0013] Furthermore, the lifting mechanism includes a drive rod rotatably connected inside the housing, the drive rod being fixedly connected to the output shaft of the second motor, a first bevel gear being fixedly connected to the bottom end of the drive rod, and two symmetrical rotating shafts being rotatably connected inside the housing, with a second bevel gear fixedly connected to one end of each of the two rotating shafts, and both second bevel gears meshing with the first bevel gear.

[0014] Furthermore, each of the two rotating shafts is fixedly connected to a take-up roller at the other end, and each of the two take-up rollers is provided with a connecting rope, the bottom end of which is connected to a vertical block.

[0015] Furthermore, the two vertical blocks are slidably connected to the two partitions respectively, and both vertical blocks are fixedly connected to the identifier.

[0016] Furthermore, the static elimination mechanism includes a rotating rod rotatably connected to the recess, the rotating rod being fixedly connected to the output shaft of the motor, two cams being fixedly connected to the rotating rod, angle rods being rotatably connected to both supports, angle plates being fixedly connected to both angle rods, and atomizing nozzles being fixedly provided at one end of each of the two angle plates. When the two atomizing nozzles reciprocate, they can spray static electricity to the staff.

[0017] Furthermore, a gear is fixedly connected to one end of each of the two angle rods, a rack is meshed on each of the two gears, and a vertical rod is fixedly connected to each of the two racks. When the two racks move up and down, they can drive the two gears to rotate.

[0018] Furthermore, each of the two recessed seats has a groove on one inner wall, and a limiting plate is slidably connected in each groove. The two limiting plates are fixedly connected to the two racks respectively. A return spring is fixedly connected in each groove, and the two return springs are fixedly connected to the two limiting plates respectively. The two limiting plates can limit the two racks to ensure their vertical movement, and at the same time support them.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The rotating shaft of this utility model drives two winding rollers to rotate and unwind the connecting rope. At the same time, two vertical blocks fall vertically using their own weight and the weight of the identifier. The two vertical blocks drive the identifier to move downward to perform security detection and verification of the worker's identity.

[0021] 2. The two racks of this utility model drive two gears to reciprocate, and the two gears drive two angle plates to reciprocate in an arc motion through two angle rods. The two angle plates drive two atomizing nozzles to reciprocate and rotate to spray evenly on the staff, thereby achieving the effect of eliminating static electricity.

[0022] 3. This utility model has a simple structure. While identifying and authenticating employees, it can also spray static electricity off employees, thereby reducing the possibility of fire, improving safety, and making it convenient for people to use. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Example 1: A safety verification device for power production sites, such as... Figures 1-3 As shown, it includes:

[0030] Casing 1;

[0031] Two partitions 2 are symmetrically fixedly installed inside the housing 1, and an identifier 3 is slidably connected between the two partitions 2; the identifier 3 is the identifier in the announcement number: CN215182062U, which is prior art and is directly referenced.

[0032] The recessed seat 4 is fixedly installed at the bottom of the identifier 3. The identifier 3 is fixedly equipped with a motor 5. Supports 6 are fixedly installed on both sides of the inner wall of the recessed seat 4. The housing 1 is equipped with a motor 7.

[0033] In this embodiment, a lifting mechanism is located inside the housing 1 and is used to lift the identifier 3. The lifting mechanism includes a drive rod 8 rotatably connected inside the housing 1. The drive rod 8 is fixedly connected to the output shaft of the motor 7. A first bevel gear 9 is fixedly connected to the bottom end of the drive rod 8. Two symmetrical rotating shafts 10 are rotatably connected inside the housing 1. A second bevel gear 11 is fixedly connected to one end of each of the two rotating shafts 10. Both second bevel gears 11 mesh with the first bevel gear 9. A take-up roller 12 is fixedly connected to the other end of each of the two rotating shafts 10. A connecting rope 13 is provided on each of the two take-up rollers 12. A vertical block 14 is connected to the bottom end of each of the two connecting ropes 13. The two vertical blocks 14 are slidably connected to the two partitions 2 respectively. Both vertical blocks 14 are fixedly connected to the identifier 3.

[0034] In this embodiment, the static elimination mechanism is mounted on the recessed seat 4 and is used to eliminate static electricity for employees undergoing identity verification. The static elimination mechanism includes a rotating rod 15 rotatably connected to the recessed seat 4. The rotating rod 15 is fixedly connected to the output shaft of the motor 5. Two cams 16 are fixedly connected to the rotating rod 15. Angle rods 17 are rotatably connected to both supports 6. Angle plates 18 are fixedly connected to both angle rods 17. Atomizing nozzles 19 are fixedly provided at one end of both angle plates 18. When the two atomizing nozzles 19 reciprocate, they can spray static electricity to the staff. Teeth are fixedly connected to one end of both angle rods 17. The wheel 20 has two gears 20, each meshing with a rack 21. Each rack 21 is fixedly connected to a vertical rod 22. When the racks 21 move up and down, they can drive the two gears 20 to rotate. Each of the two recesses 4 has a groove on one side of its inner wall. Each groove has a limiting plate 23 slidably connected to it. The two limiting plates 23 are fixedly connected to the two racks 21 respectively. Each groove has a return spring 24 fixedly connected to it. The two return springs 24 are fixedly connected to the two limiting plates 23 respectively. The two limiting plates 23 can limit the vertical movement of the two racks 21 and support them.

[0035] The implementation principle of the power production site safety verification device in this application embodiment is as follows: First, when the worker enters the housing 1, motor 5 is started, causing the output shaft of motor 5 to drive the drive rod 8 to rotate. Utilizing the meshing between the first bevel gear 9 and the two second bevel gears 11, the drive rod 8 transmits power to the rotating shaft 10. The rotating shaft 10 drives the two winding rollers 12 to rotate and unwind the connecting rope 13. Simultaneously, two vertical blocks 14 fall vertically using their own weight and the weight of the identifier 3. The two vertical blocks 14 drive the identifier 3 to move downwards to perform safety verification of the worker's identity. At the same time, the recessed seat 4 moves downwards along with the identifier 3. Motor 7 is then started, causing the output shaft of motor 7 to drive the rotating rod 15 to rotate. The rotating rod 15 drives the two cams 16 to rotate and press the two vertical rods 22 downwards. A vertical rod 22 drives two racks 21 to move downwards, and two limiting plates 23 follow the racks 21 downwards, compressing two return springs 24. When the two return springs 24 release their elasticity, they can drive the racks 21 to reset through the limiting plates 23, achieving a reciprocating lifting effect. The racks 21 drive two gears 20 to rotate reciprocally. The gears 20 drive two angle plates 18 to rotate reciprocally in an arc motion through two angle rods 17. The angle plates 18 drive two atomizing nozzles 19 to rotate reciprocally, spraying evenly on the workers, thereby achieving the effect of removing static electricity. The entire device is connected to a power supply and a main control button, which controls the device. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

Each telescopic rod 25 is fitted with a compression spring 26. An induction plate 27 is fixedly connected to the top of each telescopic rod 25. When a worker stands on the induction plate 27, the induction plate 27 compresses the compression springs 26. Simultaneously, the induction plate 27, upon sensing the pressure, sends working commands to motor 1 5 and motor 2 7. The induction plate 27 is the induction block described in publication number CN215182062U, which is prior art and is directly referenced. This application includes all structural shapes, dimensions, and materials of Example 1. These can be selected and adjusted to meet specific usage requirements.
