DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0036] See also Figures 1 to 4 The utility model is an energy-saving and safe high-temperature heat-insulating blasting structure, comprising a sleeve 1 and a heat-insulating ring 104 installed on the top thereof, a sealing groove 1042 is arranged on one side of the top of the heat-insulating ring 104, a hollow groove 1043 is opened on the other side of the top of the heat-insulating ring 104, and adjustment grooves 1044 are arranged above the front and rear ends of the hollow groove 1043, and a sealing component 2 is arranged inside the sealing groove 1042; the sealing component 2 comprises a fixed ring 201 and a movable ring 202 with a gap arranged just above it, and the bottom of the movable ring 202 is fixedly connected with connecting rods 203 at uniform intervals along the circumferential direction.

[0037] Specifically, a heat insulating structure 101 is provided on the inner wall of the sleeve 1, a weight block 102 is installed at the bottom of the sleeve 1, a mounting tube 103 is installed at the inner center position of the heat insulating ring 104, an overflow hole 1041 is opened at the inner bottom center position of the sealing groove 1042, a pull ring 2021 is fixedly connected to the top of the movable ring 202, the bottom end of the connecting rod 203 passes through the through hole on the surface of the fixed ring 201 and is connected to the pressure plate 205, a compression spring 204 is sleeved on the outer side of the outer wall of the connecting rod 203, the compression spring 204 is located between the fixed ring 201 and the pressure plate 205, the outer wall of the fixed ring 201 is fixed to the top of the inner wall of the sealing groove 1042, and a sealing ring 2051 is bonded to the outer side of the bottom of the pressure plate 205.

[0038] Furthermore, the top and bottom ends of the hollow groove 1043 are through-set, and the heat insulation structure 101, the weight block 102, etc. are existing technologies, so they are not described in detail here. An insulating water chamber is set between the sleeve 1 and the mounting tube 103, and the movable ring 202 and the pressure plate 205 are connected by the connecting rod 203 to play the role of connecting transmission. The sealing ring 2051 can play the role of sealing the connection, and the elastic performance of the compression spring 204 can drive the pressure plate 205 to move.

[0039] The operation process of this embodiment is as follows: first, water is added to the interior of the sleeve 1, and then the installation tube 103 is installed inside the sleeve 1 through the heat insulation ring 104. During the placement of the installation tube 103, the water inside the sleeve 1 will be affected by the pressure and move out from the overflow hole 1041, and will push the pressure plate 205 outside the overflow hole 1041, forcing the pressure plate 205 to move outward. The surface of the pressure plate 205 is connected to the moving ring 202 through the connecting rod 203, so the movement of the pressure plate 205 will push the moving ring 202 under the action of the connecting rod 203. And the compression spring 204 is squeezed, and then the excess water will be discharged from the overflow hole 1041 and the sealing groove 1042. At the same time, after the installation tube 103 is completely placed and the discharged water is discharged, the pressure plate 205 will be rebounded to the bottom of the sealing groove 1042 under the action of the elastic performance of the compression spring 204, and can play a sealing role under the action of the sealing ring 2051, thereby facilitating the drainage during the placement of the installation tube 103. At the same time, there is no need to seal the overflow hole 1041 after the installation of the installation tube 103 is completed, which saves time and effort and has high work efficiency. Specific embodiment 2

[0041] See also Figure 2 , Figure 3 , Figure 5 and Figure 6On the basis of the specific embodiment 1, what is different from the first embodiment is that: an inlet and outlet assembly 3 and a limit assembly 4 are provided, the inlet and outlet assembly 3 includes a water pipe 301 and a sealing plate 302 fixedly connected to its bottom end, and a fixed block 3011 is fixedly connected to the center position of the front and rear end surfaces of the water pipe 301; the limit assembly 4 includes a push plate 401 and a connecting rod 402 fixedly connected to its bottom at uniform intervals in the horizontal direction, and the other end of the connecting rod 402 sequentially penetrates the limit hole on the outer wall of the adjustment groove 1044 and the through hole on the end surface of one side of the fixing plate 403 to be connected with the block 405, thereby solving the existing problems.

[0042] Specifically, water holes 3012 are opened at the bottom of the outer wall around the water pipe 301, and telescopic rods 303 are installed on the outer side of the bottom of the sealing plate 302 at uniform intervals in the circumferential direction. The outer side of the outer wall of the telescopic rod 303 is sleeved with a return spring 304. The telescopic rod 303 and the return spring 304 are both located between the sealing plate 302 and the inner bottom end of the sealing groove 1042. The outer side of the outer wall of the connecting rod 402 is sleeved with a limit spring 404, and the limit spring 404 is located between the fixed plate 403 and the block 405.

[0043] Furthermore, the sealing plate 302 can seal the top of the hollow groove 1043, the fixed block 3011 cooperates with the clamping block 405 to limit the water flow, and the water flow can enter or discharge through the water hole 3012. The telescopic rod 303 limits the reset spring 304, and the push plate 401 and the clamping block 405 are connected by the connecting rod 402, which plays a role of connecting transmission. Under the action of the elastic performance of the limiting spring 404, the clamping block 405 can be driven to move.

[0044] The operation process of this embodiment is as follows: when the water inside the sleeve 1 needs to be replaced or added after being used for a long time, the outer end of the water pipe 301 on the surface of the protruding insulation ring 104 is pushed inward, and the outer end of the water pipe 301 is forced to push the sealing plate 302 to move into the hollow groove 1043, and will squeeze the telescopic rod 303 and the reset spring 304. At this time, the fixed block 3011 can be moved to the bottom of the block 405 and play a limiting role. At the same time, the water hole 3012 on the outer wall of the water pipe 301 can be exposed to the inside of the hollow groove 1043. At this time, the water replacement and water addition operations can be realized through the water pipe 301 and the water hole 3012. At the same time, when it is completed After completion, the front and rear push plates 401 are pushed outward, and the inner wall of the push plate 401 is connected to the block 405 through the connecting rod 402. Therefore, when the push plate 401 is moved under the force, the block 405 will be driven to move under the action of the connecting rod 402, and the limit spring 404 will be squeezed. At this time, the limiting effect of the block 405 on the fixed block 3011 can be cancelled, and then the sealing plate 302 will be pushed out under the elastic performance of the reset spring 304, and the water pipe 301 will pass through the hollow groove 1043, and the water hole 3012 will be sealed, so that it is convenient for the staff to quickly realize the water changing, water adding operations and sealing effect, saving time and effort, and high work efficiency.
