The system is usually composed of fire water sources, water supply facilities, pipe network valves, etc., including municipal water supply pipe networks, fire water pools, fire water tanks and natural water sources.

[0003] In the Chinese patent with publication number CN212522817U, a water supply device for a building fire protection system is mentioned. The device can quickly melt the frozen water inside the water storage tower through the cooperation between the heating resistor and the ice crushing structure, so as to prevent the water stored in the inner cavity of the water storage tower from freezing and becoming unusable due to excessive cold weather in winter;

[0004] However, the above device has the problem that after being used for a long time, the water circulates and the calcium, magnesium and other minerals in the water will gradually deposit on the inner wall of the tower to form scale, and the device lacks the function of directly cleaning the scale on the inner wall, which affects the normal operation of the water storage tower.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] Example 1

[0025] Reference Figure 1-2, which is the first embodiment of the utility model, and this embodiment provides a water storage tower 1, wherein a motor 11 and a hydraulic press 12 are arranged at the upper end of the water storage tower 1, a scraper member 2 is arranged at the outer end of the output end of the motor 11, a drill bit 13 is arranged at the outer end of the output end of the hydraulic press 12, and a heating pipe 14 is arranged at the lower end of the water storage tower 1; wherein the scraper member 2 includes a screw 21 arranged at the lower side of the motor 11, a slider 22 arranged on the screw 21, and support plates 23 arranged on both sides of the slider 22, a scraper 24 is arranged at the outer end of the support plate 23, and a slope 25 is arranged at the outer end of the scraper 24.

[0026] Furthermore, the motor 11 drives the screw rod 21 to rotate, and drives the slider 22 to move up and down on the screw rod 21. Since the slider 22 is fixedly connected to the support plate 23, the scraper 24 fixedly connected to the outer end of the support plate 23 is driven to move up and down.

[0027] Furthermore, the slider 22 is designed as a circular ring structure, and two groups of support plates 23 are provided on both sides of the slider 22 .

[0028] Furthermore, the hydraulic press 12 drives the output end of the hydraulic press 12 to telescopically move, thereby realizing the telescopic movement of the drill bit 13. With the help of the drill bit 13, the ice cubes in the water storage tower 1 are broken up and combined with the heating pipe 14 to accelerate the melting of the ice cubes.

[0029] Furthermore, the scraper 24 is designed as a square shaped plate, and the outer end is in contact with the inner wall of the water tower 1. With the help of the inclined surface 25 designed at the outer end of the scraper 24, when the scraper 24 moves downward, the contact area between the scraper 24 and the scale is avoided with the help of the inclined surface 25, and the friction with the scale is reduced, thereby reducing the impact of the scale on the lifting and lowering efficiency of the scraper 24.

[0030] Example 2

[0031] Reference Figure 3 , which is the second embodiment of the utility model, is different from the previous embodiment in that it includes a protection box 15 disposed on the upper end of the water storage tower 1 near the motor 11 and the hydraulic press 12, and a cavity 16 is disposed inside the protection box 15.

[0032] Specifically, a water inlet pipe 111 is provided on one side of the upper side of the water storage tower 1, a first filter plate 112 is provided in the water inlet pipe 111, and a water outlet pipe 113 is provided on the lower side of the water storage tower 1 away from the water inlet pipe 111.

[0033] Specifically, a second filter plate 114 is disposed at the lower side of the water storage tower 1 , and an angled plate 115 is disposed at the upper end of the second filter plate 114 .

[0034] Specifically, a through hole 116 is formed on one side of the angled plate 115 close to the water outlet pipe 113 , and a third filter plate 117 is disposed in the through hole 116 .

[0035] Furthermore, the motor 11 and the hydraulic press 12 are located in the cavity 16 of the protection box 15 , and the protection box 15 is used to protect the motor 11 and the hydraulic press 12 .

[0036] Furthermore, the first filter plate 112 and the third filter plate 117 play a filtering role when the water is entering and leaving, which is beneficial to ensuring the water quality. The inclined surface of the third filter plate 117 is consistent with the angled plate 115, which facilitates the scale on the upper side to roll down along the inclined surface.

[0037] Furthermore, the second filter plate 114 is provided to protect the lower heating tube 14 on the one hand, and to prevent impurities from entering the lower heating tube 14 and affecting the normal operation of the heating tube 14 on the other hand.

[0038] Furthermore, the inclined surface design of the angled plate 115 is conducive to the scale cleaned from the top to roll down along the inclined surface of the angled plate 115, making it easier for the staff to clean it later.

[0039] Example 3

[0040] Reference Figure 4 , which is the third embodiment of the utility model, is different from the previous embodiment in that it includes a support leg 118 disposed at the lower end of the water storage tower 1, and the support leg 118 is provided in six groups.

[0041] Furthermore, six groups of legs 118 are provided to help support the water storage tower 1 .

[0042] Principle, at the beginning, when the weather temperature is low, the water inside the water tower 1 begins to freeze, and the staff first starts the hydraulic press 12, and through the telescopic movement, the drill bit 13 collides and squeezes the ice surface to crush the ice, and at the same time starts the heating tube 14 to heat and melt the ice, thereby thawing the water inside the water tower 1. After being used for a long time, scale appears on the inner wall of the water tower 1, and the staff starts the motor 11 to drive the screw 21 to rotate, driving the scraper 24 to move up and down inside the water tower 1, so as to clean the inner wall of the water tower, and the cleaned scale rolls down along the bevel plate 115, which is convenient for centralized cleaning.
