Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] The present invention provides the following embodiments Example 1 The embodiment of the present invention provides, Figure 1-6 As shown, a safety auxiliary device for electrical maintenance of a thermal power plant comprises: a storage component 1, a cover component 3 is provided on an outer wall on one side of the top of the storage component 1, and handle components 2 are provided on the outer walls on both sides of the storage component 1; The storage assembly 1 includes: a storage box 4 (the storage box 4 is cylindrical), a card slot 5 is opened on the outer wall of one side of the storage box 4, the cover assembly 3 is snapped into the inside of the card slot 5, a storage area 6 is opened on one side of the inner wall of the card slot 5, and a partition assembly 7 is inserted into the storage area 6, and one end of the cover assembly 3 is inserted into the partition assembly 7.

[0024] The beneficial effects of the above technical solution are as follows: when the present invention inspects the thermal power plant, the mounting frame 13 can be pulled up by the handle belt 14, and then the worker can pull the storage assembly 1 to move on the ground, which reduces the difficulty of carrying the inspection auxiliary device, so as to facilitate the worker to carry the inspection auxiliary device. By setting the partition assembly 7, the space inside the storage area 6 can be divided, so that the tools placed inside the storage area 6 can be stored in categories. The storage box 4 and the handle assembly 2 can form a wheeled tool box, which is convenient for the worker to carry the auxiliary device on the ground, reducing the difficulty of carrying the inspection auxiliary device, so as to facilitate the worker to carry the inspection auxiliary device. Thereby effectively improving the technical problem raised by the background technology: there are many tools and parts used in the electrical inspection of the existing thermal power plant, and the maintenance personnel uniformly place the tools in the tool bag or tool box during the inspection, which makes the tool box and tool bag heavy and inconvenient for the maintenance personnel to carry with them.

[0025] Example 2 On the basis of Example 1, an electrical maintenance safety auxiliary device for a thermal power plant is provided, wherein the partition assembly 7 comprises: a mounting tube 8, a plurality of partition plates 9 with an equidistant structure are welded to the side outer wall of the mounting tube 8, and an arc plate 10 is integrally formed between two adjacent partition plates 9.

[0026] In another embodiment provided by the present invention, the cover plate assembly 3 includes: a cover plate 11, which is clamped in the card slot 5, and an insert tube 12 is integrally formed on the outer wall of one side of the cover plate 11, and the insert tube 12 is slidably inserted in the installation tube 8, and the cover plate 11 can cover the card slot 5.

[0027] In another embodiment provided by the present invention, the handle assembly 2 includes: a mounting frame 13, an outer wall on one side of the top of the mounting frame 13 is provided with a plug-in groove 16, and an outer wall on one side of the bottom of the mounting frame 13 is provided with a threaded groove 19 (the threaded groove 19 facilitates the bottom end of the plug-in rod 17 to be fixed to the mounting frame 13).

[0028] In another embodiment provided by the present invention, a handle belt 14 is installed on the outer wall of one side of the mounting frame 13 by bolts, and a power module 15 is installed on the inner wall of one side of the mounting frame 13 by bolts (the power module 15 can power the electric tools inside the storage area 6 during maintenance).

[0029] In another embodiment of the present invention, a plug-in rod 17 is inserted into the plug-in slot 16 , and the bottom end of the plug-in rod 17 is threadedly connected to the inside of the threaded slot 19 , a cross slot 18 is provided at the top of the plug-in rod 17 , and the plug-in rod 17 is inserted into the inside of the insert tube 12 .

[0030] In another embodiment provided by the present invention, the storage box 4 includes: a skeleton layer 20 (the skeleton layer 20 is made of high-strength plastic), a wear-resistant layer 22 (the wear-resistant layer 22 is made of canvas fiber) bonded to the side outer wall of the skeleton layer 20, and a rubber layer 21 sprayed on the inner wall of the skeleton layer 20.

[0031] The working principle and beneficial effects of the above technical solution are as follows: when the maintenance auxiliary device is used, the partition assembly 7 composed of the mounting tube 8, the partition plate 9 and the arc plate 10 can partition the space inside the storage area 6, so that the tools placed inside the storage area 6 can be stored in a classified manner. When the thermal power plant is subsequently overhauled, the mounting frame 13 can be pulled up by the handle belt 14, and then the worker can pull the storage assembly 1 to move on the ground, which reduces the difficulty of carrying the maintenance auxiliary device, making it convenient for the worker to carry the maintenance auxiliary device. When arriving at the maintenance site, the hand can be inserted into the cross slot 18, and Then, the plug-in rod 17 is rotated to make the plug-in rod 17 rotate inside the thread groove 19, so that the plug-in rod 17 is disengaged from the thread groove 19, thereby removing the handle assembly 2 from the storage box 4, and then the removed plug-in rod 17 is screwed into the thread groove 19, so that the mounting frame 13 forms a supporting bench, which is convenient for workers to sit when squatting for maintenance, reducing fatigue caused by long-term maintenance. At the same time, the design of the wear-resistant layer 22 can reduce the wear resistance of the storage box 4, and the rubber layer 21 can reduce the collision force between the tools inside the storage area 6 and the inner wall of the storage area 6 when the storage box 4 moves.

[0032] Example 3 On the basis of Embodiment 1-2, the electrical maintenance safety auxiliary device for a thermal power plant further includes: A weighing sensor, used to detect the total mass of the detection tools stored in the storage assembly 1; An angle detection device, used to detect the angle between the storage assembly 1 and the horizontal ground; A controller and an alarm, wherein the controller is electrically connected to the angle detection device, the weighing sensor, and the alarm, and the controller controls the alarm to work based on the angle detection device and the weighing sensor, comprising the following steps: Step 1: Calculate the maximum design length of the handlebar strap 14 according to formula (1), the angle detection device and the detection value of the weighing sensor. : (1); in is the detection value of the weighing sensor, is the running resistance coefficient between the storage assembly 1 and the ground during movement (the value range is 0.13-0.22), is the breaking force conversion coefficient of the handle belt 14 (the value range is 0.29-0.51), is the minimum breaking tensile coefficient of the handle belt 14 (the value range is 0.13-0.36), is the tensile strength of the handle belt 14, is the acceleration due to gravity, is the safety factor of the handle belt 14 (the value range is 0.53-0.74), is the mass coefficient of the handle belt 14 (the value range is 0.713-0.96), is the width of the handle belt 14, is the detection value of the angle detection device, is the cosine, is a natural constant; Step 2: According to formula (2), calculate the actual tension on the handlebar strap 14 during movement. When the actual tension of the handle belt 14 during movement exceeds the preset maximum tension value, the controller controls the alarm to sound an alarm; (2); in is the friction coefficient between the storage assembly 1 and the ground during movement (the value range is 0.10-0.37), is the thickness of the handle belt 14, is the length of the mounting frame 13, is the radius of the storage box 4.

[0033] The beneficial effects of the above technical solution are as follows: the controller calculates the target length of the handle belt 14 based on the formula (1), the angle detection device and the detection value of the weighing sensor, and comprehensively considers the running resistance coefficient between the storage component 1 and the ground during the movement, the breaking tension conversion coefficient of the handle belt 14, the minimum breaking tension coefficient of the handle belt 14, the tensile strength of the handle belt 14, the gravitational acceleration, the safety factor of the handle belt 14, the mass coefficient of the handle belt 14, and the width of the handle belt 14, so that the calculation result is more accurate and reliable; Then, according to the formula (2), the friction coefficient between the storage assembly 1 and the ground during the movement, the thickness of the handle belt 14, the length of the mounting frame 13, and the radius of the storage box 4, the actual tension exerted on the handle belt 14 during the movement is calculated, so that the calculation result is more accurate and reliable; When the controller compares the actual pulling force applied to the handle belt 14 during movement and finds that the pulling force exceeds the preset maximum pulling force, the controller controls the alarm to sound an alarm, thereby reminding the staff to promptly reduce the weight of the detection tools stored in the storage component 1 or replace the handle belt 14 with a stronger pulling force, thereby meeting the user's demand for this type of electrical maintenance safety auxiliary device for thermal power plants.
