[0018] Furthermore, the cabinet 10 is in the shape of a rectangular cabinet 10, and the detection cabin 11 is also in the shape of a rectangular parallelepiped; the number of shock-absorbing components in a detection cabin 11 is four groups, which are respectively arranged at the four edges inside the detection cabin 11; the storage plate 40 includes a bottom plate, four vertical plates and four lap plates, the bottom plate is a rectangular plate, the bottom plate is parallel to the bottom surface of the detection cabin 11, and the top surface of the bottom plate is opposite to the top surface of the detection cabin 11, the four corners of the top surface of the bottom plate are respectively connected to the bottoms of the four vertical plates, the vertical plates are perpendicular to the bottom plate, the bottom plate and the vertical plates are both located between the four shock-absorbing components, and the bottom plate and the vertical plates do not interfere with the other parts of the present invention, the top surface of the vertical plate is connected with a lap plate, the lap plate is parallel to the bottom plate, and the bottom surface of the lap plate Connect the top surface of the ring end tube 330; the detection terminal 20 and the control unit are both placed on the bottom plate of the storage board 40; the detection terminal 20 respectively adopts the distribution transformer monitoring terminal, the feeder terminal device and the distribution terminal unit; the control unit adopts a programmable controller, etc.; the shape of the spiral hose 320 is similar to the shape of a spring; the ring end tube 330 is in the shape of a circular ring, and it adopts a high-temperature resistant hard material and the material is relatively light, such as polyphenylene sulfide; the spiral hose 320 and the spray water bag 340 both adopt high-temperature resistant flexible materials, such as silicone rubber; the water pump adopts a conventional small water pump, such as a self-priming pump; the water tank is shaped like a rectangular water tank, and the water tank and the water pump are both placed outside the cabinet 10, of course, they can also be placed inside the cabinet 10.
[0019] The present invention mainly focuses on the shock absorption, cleaning, and heat dissipation of the power grid detection terminal 20; the specific operations are as follows: after the operator moves the present invention to the power grid work site, the cabinet 10 is fixed to the ground by anchor bolts, and then different detection terminals 20 are respectively installed in different detection cabins 11, thereby realizing the detection of power grid data, transformer data, and protection at the switch of the present invention. Different models of detection terminals 20 can be placed on the top surface of the storage board 40; then, turn on the water pump, and the water pump pumps the water in the water tank into the spiral hose 320, and then flows through the circular end pipe 330 and enters the spray water bag 340; when the spray water bag 340 is filled with water, turn off the water pump. Subsequently, when the storage plate 40 is pressed downward by the operator, the pressed storage plate 40 will push the circular end tube 330 connected to it downward, and the circular end tube 330 will begin to compress the spiral hose 320 and the shock-absorbing spring 310. The compressed spiral hose 320 will squeeze the water inside it into the spray water bag 340. After being squeezed, the water in the spray water bag 340 will be sprayed out through the nozzle component. The sprayed water mist is respectively directed towards the inner side of the detection cabin 11 and the hollow part inside the detection cabin 11, and cleans the dust inside the detection cabin 11, thereby preventing the detection terminal 20 equipment from malfunctioning due to dust. After cleaning is completed, the moisture inside the detection cabin 11 is cleaned. For detailed operations, please refer to the subsequent technical solution. Afterwards, the operator installs the detection terminal 20 or the control unit on the top surface of the bottom plate of the lowered storage plate 40. Since the gravity of the detection terminal 20 and the elastic force of the shock-absorbing spring 310 and the spiral hose 320 reach a state of equilibrium, the plug component 350 will not be pressurized to open, so that the water in the spray water bag 340 will not continue to spray. At the same time, the operator turns on the water pump, and the water pump begins to pump the water in the water tank back into the spiral hose 320, thereby replenishing the water in the spray water bag 340. When the water in the spray water bag 340 is refilled, the water pump is turned off again to avoid the balance between the gravity of the detection terminal 20 and the elastic force of the shock-absorbing spring 310 and the spiral hose 320 being destroyed, causing the spray component to be pressurized to open; since the spiral hose 320 and the shock-absorbing spring 310 are both squeezed, the contact area between the spiral hose 320 and the shock-absorbing spring 310 is increased compared to the normal state when no object is carried. The shock-absorbing spring 310 is in direct contact with the storage plate 40, so the heat generated by the detection terminal 20 will be transferred to the shock-absorbing spring 310 through the storage plate 40 and the circular end tube 330. The shock-absorbing spring 310 is in direct contact with the spray water bag 340, the spiral hose 320 and the circular end tube 330, so the water in the spray water bag 340, the spiral hose 320 and the circular end tube 330 can effectively help the detection terminal 20 to dissipate heat, and the contact area of the shock-absorbing spring 310 and the spiral hose 320 increases due to pressure, so the heat dissipation capacity of the shock-absorbing heat dissipation assembly 300 under pressure is further improved.The interlocking arrangement of the shock-absorbing spring 310 and the spiral hose 320 not only enhances heat dissipation but also absorbs vibration. Vibration generated by the floor is transmitted to the detection terminal 20 via the cabinet 10, effectively mitigating its impact on the detection terminal 20. Conversely, when the operator removes the detection terminal 20 or the control unit from the top surface of the bottom plate of the storage panel 40, the spiral hose 320 and the shock-absorbing spring 310 return to their normal state, and the spiral hose 320 will not be ejected from the plug 350.
[0020] As a further solution of this embodiment: the plug component 350 includes an outer plug tube 351, an inner plug tube 352, a spring spring 353 and a plug hose 354; the outer plug tube 351 is sleeved on the outside of the inner plug tube 352, and a first water outlet 3511 is provided on the side of the outer plug tube 351, and a second water outlet 3521 is provided on the side of the inner plug tube 352; the second water outlet 3521 is provided with an arc shielding plate 355, and the arc shielding plate 355 can completely cover the second water outlet 3521; a raised toggle plate 356 is provided on one side of the first water outlet 3511, and the toggle plate 356 can toggle the arc shielding plate 355; one end of the inner plug tube 352 is connected to the injection hole 341, and the other end is connected to the starting end of the inner side of the spring spring 353; The terminal end on the outside of the spring 353 is connected to the inner surface of the outer plug tube 351 and is facing one end of the plug hose 354; the other end of the plug hose 354 is connected to the spray water bag 340, and the plug hose 354 is arranged between the outer plug tube 351 and the inner plug tube 352; when the spray water bag 340 is subjected to pressure, the water in the spray water bag 340 will be sprayed to the terminal end on the outside of the clockwork spring 353 through the spray hose; when the water pressure sprayed by the spray hose is greater than the elastic force of the clockwork spring 353, the clockwork spring 353 drives the outer plug tube 351 to move together, the toggle plate 356 begins to toggle the arc baffle 355, the second water outlet 3521 opens, and the water in the spray water bag 340 is sprayed to the outside through the inner plug tube 352 and the outer plug tube 351.
[0021] Furthermore, the toggle plate 356 at the first water outlet 3511 is a raised toggle plate 356, and the toggle plate 356 can be a rectangular thin strip, which protrudes from one side of the first water outlet 3511, and the thin strip can toggle the arc baffle 355; a reset spring is provided between the inner plug tube 352 and the arc baffle 355, and the elastic force of the reset spring is relatively small so that it can rotate after being impacted by the water flow; when the arc baffle 355 leaves the toggle of the toggle plate 356, the arc baffle 355 can be reset under the action of the reset spring, thereby ensuring that the arc baffle 355 can completely seal the second water outlet 3521; the first water outlet 3511 and the second water outlet 3521 are arranged in a circumferentially staggered manner under normal conditions, and the two water outlets are adjacent.
[0022] The specific operation is as follows: when the water in the spray water bag 340 is filled with water, the squeezed spiral hose 320 will squeeze the water inside it into the spray water bag 340, and the water in the spray water bag 340 enters the spray hose under pressure. The water in the spray hose is sprayed from its opening to the terminal end of the spring 353 under pressure. When the pressure of the spray water flow is greater than the spring force of the spring 353, the spring 353 is pushed by the spray water flow, and the spring 353 is pushed. 3 drives the outer plug tube 351 to rotate around the inner plug tube 352. After the rotation, the toggle plate 356 on the water outlet side of the outer plug tube 351 will toggle the arc shielding plate 355 to rotate. As the arc shielding plate 355 moves away from the second water outlet 3521, the outer plug tube 351 and the second water outlet 3521 gradually overlap. Then, the water in the spray water bag 340 is sprayed into the interior of the inspection chamber 11 through the first water outlet 3511 and the second water outlet 3521 respectively. Conversely, when the water pressure in the spray water bag 340 is insufficient and the elastic force of the spring 353 is greater than the water pressure sprayed from the spray hose, the outer plug tube 351 begins to gradually return to its original position.
[0023] As a further solution of this embodiment: a blowing assembly 50 is provided on the inner back side of the detection cabin 11, and the blowing assembly 50 can move along the side of the detection cabin 11 and blow air into the detection cabin 11; when the storage board 40 places the detection terminal 20, the weight of the storage board 40 increases and begins to compress the shock-absorbing and heat-dissipating assembly 300, which can alleviate the vibration of the detection terminal 20 and accelerate the heat loss of the detection terminal 20; the blowing assembly 50 includes a piston cylinder 51, a piston column 52, an injection pipe 53, an intermediate hose 54 and an air pump; the piston cylinder 51 is connected to the inner side of the detection cabin 11, the piston cylinder 51 is sleeved on the outside of the piston rod, the piston rod can extend from the piston cylinder 51, the extended end of the piston rod is connected to the injection pipe 53, and the piston rod is perpendicular to the injection pipe 53; the injection pipe 53 is connected to one end of the intermediate hose 54, and the other end of the intermediate hose 54 is connected to the air pump, and a plurality of injection ports are provided on the middle side of the injection pipe 53.
[0024] Furthermore, the air blowing components 50 in one detection chamber 11 are divided into two groups, which are respectively close to the left and right sides of the interior of the detection chamber 11 and are closer to the sides of the detection chamber 11 than the shock absorbing components.
[0025] The specific operation is as follows: after the cleaning work is completed inside the detection cabin 11, the operator turns on the air pump, and the air pump starts to supply air to the intermediate hose 54. The gas enters the jet pipe 53 through the intermediate hose 54, and is finally sprayed into the interior of the detection cabin 11 through the jet port on the side of the jet pipe 53; at the same time, the piston column 52 moves along the extension and retraction of the piston cylinder 51, and the reciprocating motion of the piston column 52 and the piston cylinder 51 can be completed by conventional hydraulic or pneumatic methods, such as using an air compressor to pressurize the piston cylinder 51 to complete the reciprocating motion of the piston column 52. Since this part is a prior art, it will not be elaborated on here. When the piston column 52 moves along the extension and retraction of the piston cylinder 51, the jet pipe 53 can spray gas to different positions inside the detection cabin 11. On the one hand, it can blow away moisture and keep the inside of the detection cabin 11 dry. On the other hand, it can blow air to the surface of the detection terminal 20, thereby enhancing the heat dissipation effect of the detection terminal 20.
