Description

Technical Field

[0001] The utility model relates to the technical field of operation protection, in particular to a panel protection device. Background Art

[0002] In order to monitor whether the shear pins are normal during the debugging after unit maintenance and daily unit operation, the hydropower station has equipped the Harbin Electric units with shear pin detection equipment. However, the panels of the current shear pin detection equipment are exposed to the outside without any protection measures. During the long-term operation and daily inspection and maintenance of the hydropower generator units, since the panels of these shear pin detection equipment are not equipped with protective covers, there is a possibility of human touching the panel buttons, resulting in abnormal shear pin alarms. In addition, if the unit speed is greater than 115%, accidentally touching the shear pin detection device button for more than 5 seconds will trigger a shutdown. Therefore, it is necessary to set a protective device for it to avoid accidental touch.

[0003] Currently, most panel protections are rotating transparent protective covers. Although they can protect the panel from accidental button touching, the transparent protective cover is rotatably installed and will always hang on the back of the hand when in use. If you don't want it to hang on the back of the hand, you need to manually support it, which makes it inconvenient to operate during use. In order to solve this problem, we propose a panel protection device. Utility Model Content

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, reference Figures 1 to 3 , which is the first embodiment of the utility model, and this embodiment provides a panel protection device, which can achieve the effect on the panel of the shear pin detection equipment, including a protection mechanism 100, which includes a cover assembly 103, and also includes a reeling assembly 102 arranged on the cover assembly 103, and a protection curtain 101 fixedly connected to the reeling assembly 102, the reeling assembly 102 includes a winding rod 102a rotatably mounted on the cover assembly 103, and a coil spring 102b arranged at both ends of the winding rod 102a.

[0032] In this embodiment, the cover assembly 103 is arranged above the panel, and a fixing ear is provided on the cover assembly 103, which is fixed to the equipment by bolts. The retracting assembly 102 is arranged inside the cover assembly 103, and one end of the protective curtain 101 is fixed on the circumferential side wall of the winding rod 102a, and under the action of the coil spring 102b, the protective curtain 101 is retracted so that the other end of the protective curtain 101 is arranged at the bottom end of the cover assembly 103. When it is necessary to protect the panel, the protective curtain 101 is manually pulled downward so that the protective curtain 101 moves down to cover the panel, thereby protecting the panel to prevent people from accidentally touching the buttons on the panel.

[0033] It should be noted that the protective curtain 101 is composed of a plurality of acrylic strips connected together. When covering the panel, it has a certain strength to avoid accidental touches caused by bending and deformation.

[0034] Example 2, reference Figures 1 to 5 , which is the second embodiment of the utility model. Different from the previous embodiment, the cover assembly 103 includes a U-shaped cover 103a, end covers 103b arranged at both ends of the U-shaped cover 103a, and a limiting ring 103c arranged on the end cover 103b.

[0035] A limiting sleeve 102a-1 is provided on the circumferential side wall of the winding rod 102a, and the limiting sleeve 102a-1 and the limiting ring 103c are matched and sleeved.

[0036] In this embodiment, a coil spring 102b is provided at both ends of the winding rod 102a, one end of the winding core of the coil spring 102b is clamped with the winding rod 102a, one end of the outer ring of the coil spring 102b is clamped and fixed with the inner wall of the limiting ring 103c, and the coil spring 102b is arranged inside the limiting ring 103c, and is blocked by the limiting sleeve 102a-1, thereby preventing the coil spring 102b from escaping and scattering in the limiting ring 103c when expanding.

[0037] The winding rod 102a is rotatably mounted on one end of the end cover 103b close to the shear pin detection device panel, and the end of the end cover 103b away from the winding rod 102a is rotatably mounted with a transition rod 102c, and a vertical projection protection distance greater than 5 cm is set between the transition rod 102c and the shear pin detection device panel.

[0038] In this embodiment, the vertical projection protection distance between the transition rod 102c and the panel of the shear pin detection device is greater than 5 cm, that is, when the protective curtain 101 is pulled downward to cover the panel, the protective curtain 101 and the panel retain a safety distance, which is greater than the maximum bending distance of the protective curtain 101 when pressed in a damaged state. In other words, if the protective curtain 101 is accidentally pressed and not broken, the protective curtain 101 will not touch the button on the panel.

[0039] A U-shaped bracket 103d is disposed on one side of the bottom end of the symmetrical end cover 103b, and two vertical inner walls of the U-shaped bracket 103d are both provided with limiting grooves 103d-1 matching the protective curtain 101.

[0040] A strip groove 103a-1 is formed on one side of the bottom end of the U-shaped cover 103a, and the strip groove 103a-1 and the limiting groove 103d-1 are in the same vertical plane.

[0041] In this embodiment, fixing ears are provided on both sides of the U-shaped bracket 103d, and its U-shape is just clamped on both sides of the panel, i.e., the lower end, and then fixed on the detection equipment by bolts passing through the fixing ears. When the protective curtain 101 is pulled downward, it moves vertically downward along the limiting groove 103d-1, so that the two ends of the protective curtain 101 are limited and fixed, thereby playing a protective role.

[0042] Furthermore, the strip groove 103a-1 is a through hole for the protective curtain 101 to pass through the U-shaped cover 103a. The strip groove 103a-1 is larger than the thickness and width of the protective curtain 101, so that the protective curtain 101 can pass through the U-shaped cover 103a.

[0043] A stop bar 101a and a connecting seat 101b are provided on the end curtain plate of the protective curtain 101 away from the winding rod 102a, and the stop bar 101a is larger than the width of the strip groove 103a-1, and a pull ring 101c is rotatably installed on the connecting seat 101b, and a hand pressure rod 101d is provided on the pull ring 101c, and a clamping seat 103d-2 is provided on one side of the horizontal section of the U-shaped bracket 103d, and the clamping seat 103d-2 is used for sleeve-fixing the pull ring 101c.

[0044] In this embodiment, the hand pressure rod 101d is provided to facilitate pressing the pull ring 101c downward so that the pull ring 101c disengages from the clamping seat 103d-2, thereby unlocking the protective curtain 101. After the protective curtain 101 is unlocked, under the action of the winding spring 102b, the protective curtain 101 is rolled up by the winding rod 102a, so that the panel is exposed. When the baffle bar 101a is rolled up to the strip groove 103a-1, the baffle bar 101a is larger than the width of the strip groove 103a-1, so that the protective curtain 101 cannot be further rolled up, so that one end of the protective curtain 101 is under the U-shaped cover 103a, avoiding the situation of entering the U-shaped cover 103a.

[0045] The rest of the structure is the same as that of Example 1.

[0046] Example 3, reference Figures 1 to 7 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a buffer mechanism 200, which solves the problem that after the protective curtain 101 is unlocked and opened, it is quickly rolled up by the winding rod 102a under the action of the coil spring 102b, causing the blocking bar 101a at the end of the protective curtain 101 and the strip groove 103a-1 at the bottom of the U-shaped cover 103a to collide and be damaged. The embodiment includes the protective mechanism 100 in the above embodiment, and also includes a buffer mechanism 200 arranged on one side of the inner wall of the U-shaped cover 103a. The buffer mechanism 200 includes a friction component 201 rotatably mounted on the inner wall of the U-shaped cover 103a, and an elastic member 202 arranged on the friction component 201.

[0047] The friction assembly 201 includes a driving plate 201a rotatably mounted on the inner wall of the U-shaped cover 103a, a rubber pad 201b disposed on the driving plate 201a, and a pressure plate 201c disposed on the driving plate 201a.

[0048] The pressing plate 201c and the driving plate 201a are arranged vertically, and a clamping end 201d is arranged at one end of the pressing plate 201c away from the driving plate 201a.

[0049] In this embodiment, the buffer mechanism 200 is arranged on one side of the winding rod 102a, and the driving plate 201a is pushed by the elastic force of the elastic member 202, so that the rubber pad 201b on the driving plate 201a is always in contact with the protective curtain 101 on the side wall of the winding rod 102a, so that when the protective curtain 101 is rolled up by the winding rod 102a, there is a certain resistance, which reduces the winding speed of the winding rod 102a. As the winding rod 102a is rolled up more, the outer diameter of the protective curtain 101 on the winding rod 102a increases, thereby squeezing the driving plate 201a, increasing the elastic force of the elastic member 202, and making the winding speed slower and slower.

[0050] Furthermore, the outer diameter of the rolled-up protective curtain 101 becomes larger and larger. When squeezing the driving plate 201a, the driving rod 201a is driven to rotate, so that the pressure plate 201c gradually approaches the protective curtain 101, and finally presses the protective curtain 101, thereby achieving braking efficiency, making the speed of the protective curtain 101 smaller and smaller during the rolling-up process, so that when the baffle bar 101a on the protective curtain 101 collides with the strip groove 103a-1 at the bottom end of the U-shaped cover 103a, its speed is almost stopped, thereby protecting the protective curtain 101 and avoiding the protective curtain 101 from being damaged due to collision.

[0051] It should be noted that the clamping end 201d is made of rubber material, and the pressure plate 201c presses the protective curtain 101 mainly through the resistance between the clamping end 201d at its end and the protective curtain 101. Because the protective curtain 101 is composed of multiple acrylic plates connected in series, there are gaps between the acrylic plates. When the protective curtain 101 is rolled up, the clamping end 201d frequently bounces out of the gap due to deformation, thereby greatly improving its deceleration effect.

[0052] The rest of the structure is the same as that of Example 2.

[0053] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model.

Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0054] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.

[0055] It should be understood that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made.
