Description

Technical Field

[0001] The present invention relates to the technical field of antifreeze devices, and particularly to an antifreeze structure and an antifreeze suction pipe. Background Art

[0002] In an outdoor environment, the water pipes of an uncovered water tank are prone to situations such as frozen pipe walls and corroded pipe bodies due to the influence of the external environment, and the service life of the water pipes is generally short. Especially in winter, the uncovered water tank outdoors will freeze. When the suction pipe is inserted into the water tank and the water pump stops sucking water, the water in the suction pipe may freeze. If we want to prevent the suction pipe from freezing, we need to heat the water in the suction pipe. However, since the water inside and outside the suction pipe in the outdoor water tank is below 0°C, traditional heating devices insert heating rods into the water pipes or fix them on the inner wall of the water pipes. When heating is not required, the heating devices in the suction pipe occupy a large amount of space inside the suction pipe, affecting the water suction efficiency of the suction pipe; when heating, one side of the heating device is in direct contact with the water to be frozen, and the other side is in direct contact with the pipe wall, often causing damage to the heating device or uneven heat absorption and damage to the suction pipe. There are also some heating devices arranged on the outer wall of the suction pipe, but when heating, they not only heat the suction pipe but also heat the water in the water tank, consuming a large amount of heat and electricity. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and provide an antifreeze structure and an antifreeze suction pipe. The antifreeze structure can protect the suction pipe while preventing the suction pipe in an open-air water tank from freezing with low energy consumption.

[0004] To achieve the above purpose, on the one hand, the present invention provides an antifreeze structure. The antifreeze structure includes a suction pipe body inserted into the water tank and a heat preservation sleeve sleeved outside the suction pipe body. A vacuum sealed cavity is formed by enclosing the outer wall surface of the suction pipe body and the inner wall surface of the heat preservation sleeve. A heating device is laid in the sealed cavity, and the heating device is configured to be able to heat the suction pipe body.

[0005] Preferably, the heating device includes a heater and a sleeve heat insulation part arranged around the side of the heater away from the suction pipe body. Among them, the heater is configured to be able to heat the suction pipe body and can be insulated by the sleeve heat insulation part.

[0006] Preferably, the heating device further includes a suction pipe heat preservation part arranged on the side of the heater facing the suction pipe body. The suction pipe heat preservation part fits on the outer wall surface of the suction pipe body. Among them, the thickness of the suction pipe heat preservation part is less than the thickness of the sleeve heat insulation part.

[0007] Preferably, the anti-freezing structure further includes a control unit connected to the heater, and the control unit is configured to control the operation of the heater.

[0008] Preferably, a temperature sensor connected to the control unit is further provided on the outer wall of the water suction pipe body, and the temperature sensor is configured to measure the temperature of the water suction pipe body and transmit the measurement result to the control unit.

[0009] Preferably, the temperature sensor includes a low-level temperature sensor and a high-level temperature sensor. The high-level temperature sensor is provided on the outer wall of the water suction pipe body at a position 0.5 m below the highest liquid level of the water tank, and the low-level temperature sensor is provided on the outer wall of the water suction pipe body at a position 0.2 m above the lowest liquid level of the water tank.

[0010] Preferably, the outer wall of the heat preservation sleeve has a waterproof part, and the waterproof part is configured to provide waterproof protection for the anti-freezing structure.

[0011] On the other hand, the present invention provides an anti-freezing water suction pipe, which includes a water pump arranged at the edge of a water tank, a fixing part arranged in the water tank, and the above anti-freezing structure. Among them, the water pump is communicated with the water suction pipe body so as to be able to suck water from the water tank through the water suction pipe body, and the fixing part is configured to fix the anti-freezing structure in the water tank.

[0012] Preferably, the fixing part includes a water suction pipe riser bracket arranged at the bottom of the water tank, and the water suction pipe riser bracket is connected to the water suction port at one end of the water suction pipe body far away from the water pump so as to be able to fix the water suction port to the bottom of the water tank.

[0013] Preferably, the fixing part further includes a water suction pipe side wall bracket arranged on the side wall of the water tank, and the water suction pipe side wall bracket is connected to the outer wall of the anti-freezing structure so as to be able to fix the anti-freezing structure to the side wall of the water tank;

[0014] Preferably, there are a plurality of the water suction pipe side wall brackets, and the plurality of water suction pipe side wall brackets are arranged at intervals on the side wall of the water tank so as to provide support for the anti-freezing structure in the vertical direction.

[0015] Through the above technical solutions, sealing and vacuum pumping are carried out between the outer side of the water suction pipe body and the heat preservation sleeve. The heating device laid in the sealed cavity can conduct heat evenly to the water suction pipe body in a vacuum environment, avoiding the explosion of the water suction pipe body caused by sudden heating in a low-temperature environment.

[0022] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0023] On the one hand, the present invention provides an anti-freezing structure, as Figure 1 shown, the anti-freezing structure includes a water suction pipe body 20 inserted into the water tank 120 and a heat preservation sleeve 40 sleeved outside the water suction pipe body 20. A vacuum sealing cavity is formed by enclosing the outer wall surface of the water suction pipe body 20 and the inner wall surface of the heat preservation sleeve 40. A heating device is laid in the sealing cavity, and the heating device is arranged to be able to heat the water suction pipe body 20.

[0024] In the present invention, a seal is formed between the outer wall of the water suction pipe body 20 and the inner wall of the heat preservation sleeve 40 to form a completely sealed space. The heating device is laid in the sealed cavity, and the sealed cavity is evacuated so that the vacuum degree in the sealed cavity is 0 to -100 kPa. The heating device laid in the sealed cavity can conduct heat evenly to the water suction pipe body 20 in a vacuum environment, avoiding the pipe body of the water suction pipe 20 from bursting due to sudden heating in a low-temperature environment. The heat preservation sleeve 40 plays a role in waterproofing and heat insulation for the heating device, preventing the heating device from transferring heat to the water in the water tank 120 while heating the water suction pipe body 20, reducing the heat loss of the heating device, and saving energy and electricity.

[0025] To further monitor the vacuum degree in the sealed cavity, a vacuum pressure gauge is provided at the top of the sealed cavity.

[0026] In an embodiment of the present invention, the heating device includes a heater 30 and a sleeve heat insulation part 50 disposed around the side of the heater 30 away from the water suction pipe body 20. Among them, the heater 30 is configured to be able to heat the water suction pipe body 20 and can be insulated by the sleeve heat insulation part 50.

[0027] Among them, the heater 30 can have any suitable heating form. Preferably, the heater 30 is an electric heating tape wound in a dense manner, and the power per meter of the electric heating tape is 0.5 to 1 kW to be able to heat the water suction pipe body 20 evenly.

[0028] In addition, the sleeve heat insulation part 50 is made of a material capable of heat insulation and heat preservation, such as heat insulation soft felt, refractory asbestos, etc. Preferably, the sleeve heat insulation part 50 is made of rubber and plastic insulation cotton, and its thickness is set to 100 to 300 mm to be able to play a role in heat insulation between the heater 30 and the heat preservation sleeve 40, preventing the heater 30 from transferring heat to the heat preservation sleeve 40 and the water in the water tank 120 while heating the water suction pipe body 20, and being able to protect the heater 30, waterproof and insulate, and keep the heat generated by the heater 30.

[0029] In order to provide protection and heat preservation for the water suction pipe body 20 while avoiding damage to the water suction pipe body 20 due to too fast heating or too high heating temperature and preventing the heating effect of the heater 30 on the water suction pipe body 20 from being affected, the heating device further includes a water suction pipe heat preservation part 60 disposed on the side of the heater 30 facing the water suction pipe body 20, and the water suction pipe heat preservation part 60 is attached to the outer wall surface of the water suction pipe body 20.

[0030] Further, the thickness of the water suction pipe heat preservation part 60 is much smaller than that of the sleeve heat insulation part 50. In a preferred mode, the thickness of the water suction pipe heat preservation part 60 is set to be 10-50 mm, and the thickness of the sleeve heat insulation part 50 is set to be 100-300 mm, so as to ensure that when the heater 30 heats the water suction pipe body 20, heat transfer to the heat preservation sleeve 40 and the water in the water tank 120 will not occur, thereby reducing the heat loss of the heating device. Among them, the water suction pipe heat preservation part 60 preferably adopts waterproof and insulating rubber and plastic heat preservation cotton.

[0031] In addition, the anti-freezing structure further includes a control part 110 connected to the heater 30, and the control part 110 is set to be able to control the operation of the heater 30. Specifically, the control part 110 controls the turning on and off of the heater 30 according to the temperature of the outdoor environment, so as to prevent the water suction pipe body 20 from freezing.

[0032] In an embodiment of the present invention, a temperature sensor connected to the control part 110 is further provided on the outer wall of the water suction pipe body 20. The temperature sensor is set to be able to measure the temperature of the water suction pipe body 20 and transmit the measurement result to the control part 110. The temperature sensor transmits the measured temperature to the control part 110. When the temperature of the water suction pipe body 20 is lower than 0°C, the water in the pipe has the risk of freezing. At this time, the control part 110 controls the heater 30 to operate to heat the water suction pipe body 20; when the temperature of the water suction pipe body 20 rises to reach 3-8°C, the control part 110 controls the heater 30 to disconnect the heating to avoid energy waste.

[0033] Further, the temperature sensor includes a low - level temperature sensor 70 and a high - level temperature sensor 90. Taking the common depth of 4m of the water tank 120 as an example, the water surface of the water tank 120 is the standard surface, the elevation of the water surface is 0.00m, and the bottom of the tank is - 4.0m. The high - level temperature sensor 90 is arranged on the outer wall of the water suction pipe body 20 at 0.5m below the water surface of the water tank 120, that is, at an elevation of - 0.5m; the low - level temperature sensor 70 is arranged on the outer wall of the water suction pipe body 20 at 0.2m from the bottom of the water tank 120, that is, at - 3.8m. During use, the low - level temperature sensor 70 and the high - level temperature sensor 90 simultaneously measure the temperature of the water suction pipe body 20. At high water levels, the temperatures detected by the two sensors are basically the same; when the water level is low, the low - level temperature sensor 70 detects the temperature and transmits the result to the control unit 110 for calculation and interlock adjustment, and the temperature detected by the high - level temperature sensor 90 is also transmitted to the control unit 110 for feedback adjustment. When the temperature difference between the upper and lower temperature measurement points exceeds 30°C, the heating amount of the heater 30 is reduced to avoid energy waste.

[0034] Since the anti - freezing structure is immersed in water for a long time, to prevent water from entering the anti - freezing structure, causing damage to the heating device when it touches water or the outer wall of the heat - insulating sleeve 40 has a waterproof part, and the waterproof part is arranged to provide waterproof protection for the anti - freezing structure.

[0035] On the other hand, the present invention provides an anti - freezing water suction pipe, which includes a water pump 10 arranged at the edge of the water tank 120, a fixing part arranged in the water tank 120, and the above - mentioned anti - freezing structure. Among them, the water pump 10 is connected to the water suction pipe body 20 so as to be able to suck water from the water tank 120 through the water suction pipe body 20, and the fixing part is arranged to be able to fix the anti - freezing structure in the water tank 120. Specifically, when the water in the water tank 120 begins to freeze, the heating device in the anti - freezing structure uniformly heats the water suction pipe body 20, so that the water temperature in the water suction pipe body 20 remains above 0°C, and at the same time, it is avoided that the heating device also transfers heat to the water in the water tank 120, reducing the heat loss of the heating device and saving energy and electricity.

[0036] Among them, the fixing part includes a suction pipe riser bracket 80 arranged at the bottom of the pool 120 of the water tank. The suction pipe riser bracket 80 is connected to the water suction port at one end of the suction pipe body 20 away from the water pump 10, so as to fix the water suction port to the bottom of the pool 120. Specifically, the suction pipe riser bracket 80 is fixed to the bottom of the pool 120 and connected to the water suction port through a pipe clamp, so that the water suction port is fixed to the bottom of the pool 120, ensuring that the anti-freezing suction pipe can suck out all the water in the pool 120.

[0037] In addition, the fixing part further includes a suction pipe side wall bracket 100 arranged on the side wall of the pool 120. The suction pipe side wall bracket 100 is connected to the outer wall of the anti-freezing structure through a pipe clamp, so as to fix the anti-freezing structure to the side wall of the pool 120.

[0038] In an embodiment of the present invention, there are multiple suction pipe side wall brackets 100. The multiple suction pipe side wall brackets 100 are arranged at intervals on the side wall of the pool 120, so as to provide support for the anti-freezing structure in the vertical direction.

[0039] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0040] In addition, it should be noted that, in the case of no contradiction, the various specific technical features described in the above specific embodiments can be combined in any suitable way. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.

[0041] In addition, any combination can be made between various different embodiments of the present invention, as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
