[0022] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a spray device for the extrusion outlet of a heat preservation pipe through improvement. The technical solution of the present utility model is:

[0024] As Figures 1 - 3As shown in the figure, a spray device for the extrusion outlet of a heat-insulating pipe includes a water tank 1. A fixed box 4 is fixedly connected to the water tank 1. The fixed box 4 is of a hollow structure, and the cross-section of the fixed box 4 is in a shape of a Chinese character 'hui'. A spray assembly 5 and an adjustment assembly 6 are provided on the fixed box 4. The spray assembly 5 includes a water pump 51, a water suction pipe 52, a water outlet pipe 53, a hose 54, a nozzle 55 and a spray hole 56. The water pump 51 is fixedly connected inside the water tank 1. The water suction pipe 52 is fixedly connected to the water pump 51. The two ends of the water outlet pipe 53 are respectively fixedly connected to the water pump 51 and the fixed box 4. Four hoses 54 are fixedly connected to the fixed box 4. The hose 54 has good ductility and can be stretched for use. At the interface between the hose 54 and the fixed box 4, a pressure valve is provided to ensure that the four nozzles 55 can spray water simultaneously. The four nozzles 55 are respectively fixedly connected to the four hoses 54. A plurality of spray holes 56 are respectively opened on the four nozzles 55. The adjustment assembly 6 includes a slider 63 and a rotating plate 64. Eight sliders 63 are slidably connected to the fixed box 4. The two sliders 63 on the same side are symmetrical about the hose 54. The two ends of the eight rotating plates 64 are respectively rotatably connected to the eight sliders 63 and the four nozzles 55.

[0025] Further, as Figures 1 - 3 shown, the adjustment assembly 6 further includes a motor 61 and a first bidirectional screw 62. The motor 61 is fixed to the fixed box 4 by bolts. One of the first bidirectional screws 62 is fixed to the output shaft of the motor 61 by bolts, and the other first bidirectional screw 62 is rotatably connected to the fixed box 4. The four sliders 63 are respectively threadedly connected to the two ends of the two first bidirectional screws 62. The two first bidirectional screws 62 are symmetrical about the water pump 51. The length of the first bidirectional screw 62 is equal to the inner wall height of the fixed box 4.

[0026] Further, as Figures 1 - 3 shown, the adjustment assembly 6 further includes a second bidirectional screw 65 and a fixed block 66. The two fixed blocks 66 are fixedly connected to the fixed box 4. The two second bidirectional screws 65 are respectively rotatably connected to the two fixed blocks 66. The two second bidirectional screws 65 are symmetrical about the horizontal hose 54. The four sliders 63 are respectively threadedly connected to the two ends of the two second bidirectional screws 65.

[0027] Further, as Figures 1 - 3 shown, the adjustment assembly 6 further includes a bevel gear one 67 and a bevel gear two 68. The four bevel gears one 67 are respectively fixedly connected to the two ends of the two first bidirectional screws 62. The four bevel gears two 68 are respectively fixedly connected to the two ends of the two second bidirectional screws 65. The bevel gear one 67 meshes with the bevel gear two 68. The diameter of the bevel gear one 67 is the same as the diameter of the bevel gear two 68.

[0028] Further, as Figure 1 and Figure 3As shown in the figure, a fixing frame 2 and a filter screen 3 are provided on the water tank 1. Four fixing frames 2 are fixedly connected to the water tank 1, and two filter screens 3 are respectively slidably connected to the four fixing frames 2. The filter screen 3 can be pulled out from the fixing frame 2 for cleaning.

[0029] Furthermore, as Figures 1 - 3 shown in the figure, a drain pipe 7 is provided on the water tank 1. The drain pipe 7 is fixedly connected to the water tank 1, and a valve is provided on the drain pipe 7. When the water in the water tank 1 is turbid, the valve can be opened to drain the water in the water tank 1 for replacement.

[0030] The specific working method is as follows: Water is injected into the water tank 1 through the filter screen 3. The water pump 51 is started. The water pump 51 pumps water from the water tank 1 to the outlet pipe 53 through the suction pipe 52, and then flows into the fixed box 4 through the outlet pipe 53, enters the nozzle 55 through the hose 54, and is sprayed out through the spray holes 56 to spray the surface of the heat preservation pipe. When the size of the heat preservation pipe changes, the motor 61 is started, and its output shaft rotates to drive the first bidirectional screw 62 to rotate. Since the slider 63 is threadedly connected to the first bidirectional screw 62, the two sliders 63 on the first bidirectional screw 62 move towards each other, driving the two rotating plates 64 to rotate, pushing the nozzle 55 to move inwards, so that the distance between the two nozzles 55 in the horizontal direction decreases. Since the bevel gear 67 meshes with the bevel gear 68, the bevel gear 67 drives the bevel gear 68 to rotate under the rotation of the first bidirectional screw 62, and the second bidirectional screw 65 also rotates accordingly, causing the two sliders 63 on it to move towards each other, and the distance between the two nozzles 55 in the vertical direction decreases. The first bidirectional screw 62 far from the motor 61 also rotates under the action of the bevel gear 67 and the bevel gear 68, driving the nozzle 55 to move inwards. At this time, all four nozzles 55 move inwards. After the adjustment is completed, the motor 61 can be turned off. By reducing the distance between the nozzle 55 and the surface of the heat preservation pipe, the spray cooling effect is better.

[0031] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above technical means, but also include the technical solutions composed of equivalent replacements of the above technical features. The matters not covered by the present utility model belong to the common general knowledge of those skilled in the art.
