Description

[Technical field]

[0001] The utility model relates to a protective device based on equipment installation technology, belonging to the field of equipment installation protective devices. [Background technology]

[0002] As the demand for electricity consumption gradually increases, the after-sales maintenance of power equipment has become more and more important. However, power safety accidents occur frequently. Most of them are caused by non-standard construction, especially forgetting to turn on the power switch or incomplete power outage, which causes great harm to the lives of workers.

[0003] During the inspection and maintenance of power equipment, it is a relatively safe protection measure to cut off the power supply to a single power box. Therefore, it is particularly important to equip the power box with a safe auxiliary power-off controller. However, traditional power-off controllers can only achieve stable connection or have a high probability of false touch when cutting off, which cannot effectively ensure the personal safety of workers.

[0004] In order to ensure that the power off controller can stably connect and work when the power equipment is in normal operation, and can quickly and effectively cut off the power when the power equipment is in maintenance state, the utility model is proposed to realize dual efficient control of power off controller connection and power off. [Contents of the utility model]

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a protective device based on equipment installation technology, which can ensure that when the protective device is in normal operation, the power-off controller can be stably connected to achieve operation. At the same time, when the power equipment is in maintenance or installation, the power-off controller can quickly and effectively cut off the power.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A protective device based on equipment installation technology includes an electrical box and a power-off controller. The main power supply is connected and controlled in the power-off controller. The power-off controller is fixedly connected to a power connector. An arc-shaped spring is fixedly connected to one end of the power connector. A propulsion seat is also slidably connected in the power-off controller. The outer end of the propulsion seat is located outside the power-off controller. The inner end of the propulsion seat is connected to an extrusion rod that matches the arc-shaped spring. An auxiliary feed pipe is provided at one end of the extrusion rod. The auxiliary feed pipe is in the shape of a column tube. The other end of the extrusion rod is fixedly connected to the propulsion seat.

[0008] The beneficial effects of adopting the utility model are:

[0009] First, the protective device includes an electrical box for storing electrical equipment and a power-off controller for ensuring safe power-off of a single electrical box. The power of a single electrical box is connected and controlled in the power-off controller. The power-off controller is fixedly connected to a power connector. An arc-shaped spring is fixedly connected to one end of the power connector. The arc-shaped springs are back-to-back with each other. In the utility model, there are two arc-shaped springs, which are back-to-back arranged so that the springs clamp the extrusion rod with their own elasticity, ensuring that the extrusion rod is stably connected to the power connector and preventing accidental touch. When the power-off controller needs to cut off the power, the elasticity of the spring effectively prevents the extrusion rod from accidentally touching the power connector.

[0010] In addition, in the utility model, a propulsion seat is slidably connected inside the power-off controller, and the outer end of the propulsion seat is located outside the power-off controller. The propulsion seat is arranged outside, which is convenient for the staff to use their feet to push the extrusion rod with less effort. The inner end of the propulsion seat is connected to an extrusion rod that matches the arc-shaped spring leaf. The diameter of the extrusion rod is smaller than that of the propulsion seat. The reduced area at the top of the extrusion rod is conducive to increasing force, thereby prompting the extrusion rod to separate the spring leaf and contact the power connector.

[0011] Secondly, in the utility model, an auxiliary feed tube is provided at one end of the extrusion rod. The auxiliary feed tube is in the shape of a column tube. The auxiliary feed tube guides the moving direction of the extrusion rod to prevent the extrusion rod from being pushed incorrectly and damaging the inside of the power-off controller, thereby extending the service life of the power-off controller. The other end of the extrusion rod is fixedly connected to the propulsion seat.

[0012] Preferably, both ends of the power connector are connected with an inlet connector and an outlet connector which are slidably connected to the power source.

[0013] Preferably, a protection device is further included, which includes a protection tube, one end of the protection tube is provided with a first opening inwardly, and the first opening is connected to the auxiliary inlet tube.

[0014] Preferably, the other end of the protective tube is provided with a second opening, the second opening is connected with a clamping jaw member extending outward, the clamping jaw member is provided with a clamping jaw block, and the clamping jaw block is used for the clamping jaw to push the seat to pull out the extrusion rod.

[0015] Preferably, the protective device further comprises a spring, the spring is sleeved on the outside of the auxiliary feed pipe and the propulsion seat, and the auxiliary feed pipe is sleeved on the outside of the extrusion rod.

[0016] Preferably, a blocking block is provided at the second opening, and the blocking block abuts against the clamping jaw block. When the clamping jaw block and the blocking block abut against each other, the spring abuts against the other end of the clamping jaw block to make the clamping jaw block and the blocking block in close contact.

[0017] Preferably, the clamping jaw block self-rotates in the protective tube, and when the clamping jaw block self-rotates and does not abut against the blocking block, the clamping jaw of the clamping jaw block pushes the seat, and the seat is pulled out together with the extrusion rod.

[0018] Preferably, the diameter of the propulsion seat is smaller than that of the auxiliary feed tube.

[0019] Preferably, the diameter of the extrusion rod is smaller than that of the auxiliary inlet tube, and the top end of the extrusion rod is a spherical body.

[0020] Preferably, a displacement sensor is provided inside the power-off controller, and the displacement sensor is used to monitor the distance between the extrusion rod and the power connector.

[0021] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0034] Embodiment 1:

[0035] This embodiment shows a protective device based on equipment installation technology, such as Figure 1-5 As shown, it includes an electrical box 1 for storing electrical equipment and a power-off controller 2 for ensuring safe power-off of a single electrical box 1. The power supply of a single electrical box 1 is connected and controlled in the power-off controller 2. The power-off controller 2 is fixedly connected to a power connector 3. An arc-shaped spring sheet 4 is fixedly connected to one end of the power connector 3. The arc-shaped spring sheets 4 are back-to-back with each other. In the utility model, there are two arc-shaped spring sheets 4. The two spring sheets are back-to-back arranged so that the spring sheets clamp the extrusion rod 6 with their own elasticity, ensuring that the extrusion rod 6 is stably connected to the power connector 3 and preventing accidental touch. When the power-off controller 2 needs to be powered off, the elasticity of the spring sheet effectively prevents the extrusion rod 6 from accidentally touching the power connector 3.

[0036] In addition, in the utility model, a propulsion seat 5 is also slidably connected inside the power-off controller 2. The outer end of the propulsion seat 5 is located outside the power-off controller 2. The propulsion seat 5 is arranged outside, which is convenient for the staff to use their feet to push the extrusion rod 6 with less effort. The inner end of the propulsion seat 5 is connected to the extrusion rod 6 that cooperates with the arc-shaped spring leaf 4. The diameter of the extrusion rod 6 is smaller than that of the propulsion seat 5. The reduced area at the top of the extrusion rod 6 is conducive to increasing the force, thereby prompting the extrusion rod 6 to separate the spring leaf and contact the power connector 3.

[0037] Secondly, in the utility model, an auxiliary feed tube 7 is provided at one end of the extrusion rod 6. The auxiliary feed tube 7 is in the shape of a column tube. The auxiliary feed tube 7 guides the moving direction of the extrusion rod 6 to prevent the extrusion rod 6 from being pushed incorrectly and damaging the inside of the power-off controller 2, thereby extending the service life of the power-off controller 2. The other end of the extrusion rod 6 is fixedly connected to the propulsion seat 5.

[0038] like Figure 3 As shown, both ends of the power connector 3 are connected with an incoming wire connector 8 and an outgoing wire connector 9 which are slidably connected to the power source. The incoming wire connector 8 is connected to the incoming wires, and the outgoing wire connector 9 is connected to the outgoing wires. The power connector 3 is provided with a groove which matches the shape of the extrusion rod 6. When the extrusion rod 6 is in close contact with the power connector 3 through the groove, the incoming wire connector 8 and the outgoing wire connector 9 are electrically connected, and the inside of the electrical box 1 is energized.

[0039] like Figure 4 As shown, it also includes a protective device 10, and the protective device 10 includes a protective tube 101. The protective tube 101 can also push away the arc-shaped spring sheet 4 to facilitate the extrusion rod 6 to contact the power connector 3. It should be noted that a groove can be provided at the place where the power connector 3 contacts the extrusion rod 6 to facilitate contact between the two. A first opening 11 is opened inward at one end of the protective tube 101, and the first opening 11 is connected to the auxiliary feed tube 7. The auxiliary feed tube 7 guides the direction of travel of the extrusion rod 6 to prevent the extrusion rod 6 from being pushed incorrectly and damaging the inside of the power-off controller 2, thereby extending the service life of the power-off controller 2.

[0040] The other end of the protective tube 101 is provided with a second opening 12, and the second opening 12 is connected to a clamping claw member 13 extending outward, and the clamping claw member 13 extends to the outside of the electrical box 1. The clamping claw member 13 is provided with a clamping claw block 14. In the utility model, there are two clamping claw members 13. When the electrical box 1 needs to be powered off for maintenance, the staff can operate the clamping claw blocks 14 to rotate them to be in a clamping state with each other, such as using chopsticks. The clamping claw block 14 clamps the push seat 5 to pull out the extrusion rod 6; when the electrical box 1 needs to be in a normal working state, the clamping claw blocks 14 are reversed and located on both sides of the protective tube 101.

[0041] The protective device 10 also includes a spring 102, which is sleeved on the outside of the auxiliary feed tube 7 and the propulsion seat 5. The other end of the spring 102 contacts the clamping jaw block 14. The elastic force of the spring 102 causes the clamping jaw block 14 to be in close contact with the protective tube 101. When the clamping action of the clamping jaw block 14 is used, the clamping piece will push inward to form pressure on the spring 102. After the clamping action of the clamping jaw block 14 is used, the compression spring reacts to the clamping jaw block 14, causing the clamping jaw block 14 to return to a state of contact with the protective tube 101. The auxiliary feed tube 7 is sleeved on the outside of the extrusion rod 6.

[0042] like Figure 1-6As shown, a blocking block 15 is provided at the second opening 12, and the blocking block 15 and the clamping jaw block 14 abut against each other, and the abutment method can be snap-fitting. Of course, as long as the blocking block 15 and the clamping jaw block 14 can achieve abutment with each other, they fall within the protection scope of the utility model, such as magnetic attraction.

[0043] When the clamping jaw block 14 and the blocking block 15 abut against each other, the spring 102 abuts against the other end of the clamping jaw block 14 to make the clamping jaw block 14 and the blocking block 15 in close contact.

[0044] The clamping jaw block 14 rotates in the protective tube 101. It should be noted that the outside of the clamping jaw 13 is wrapped with an anti-electric film to prevent the staff from getting an electric shock when clamping the propulsion seat 5. When the clamping jaw block 14 rotates and does not abut against the blocking block 15, the clamping jaw block 14 clamps the propulsion seat 5, and the propulsion seat 5 is pulled out together with the extrusion rod 6.

[0045] like Figure 7 As shown, the diameter of the push seat 5 is smaller than the auxiliary feed pipe 7, and no force friction will be generated, so that the staff can save effort in pushing or clamping and taking out.

[0046] The diameter of the extrusion rod 6 is smaller than the auxiliary inlet tube 7, the top end area of ​​the extrusion rod 6 is small, and the top end of the extrusion rod 6 is spherical, which is more conducive to the extrusion rod 6 to separate the arc spring 4 and achieve more labor-saving contact with the power contact head.

[0047] A displacement sensor 16 is provided inside the power-off controller 2, and the displacement sensor 16 is used to monitor the distance between the extrusion rod 6 and the power connector 3. When the displacement sensor 16 detects that the distance between the extrusion rod 6 and the power connector 3 is 0, a beeping warning sound is emitted to prompt the staff to successfully connect the power inside the electric box 1.

[0048] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention shall be included in the scope of the claims.
