Description

Technical Field

[0001] This utility model relates to the field of fire protection technology for ancient buildings, specifically to an antifreeze booster pump set for fire water systems in ancient buildings. Background Technology

[0002] In cold regions, the issue of freezing prevention for fire water systems in ancient buildings has always been a key challenge in the field of fire safety. Due to their unique historical value and architectural structure, ancient buildings have extremely high requirements for the reliability of their fire protection systems. In low-temperature environments, the booster pump sets in the fire water systems are very susceptible to damage due to freezing, which can lead to the inability to supply fire water normally and seriously threaten the fire safety of ancient buildings. Therefore, highly reliable antifreeze booster pump sets are needed.

[0003] Existing antifreeze booster pump sets, such as common self-priming booster pumps, rely on pre-stored water inside the pump to achieve self-priming. To prevent the water inside the pump head from freezing in low-temperature environments, these pump sets are usually equipped with temperature sensors to monitor the water temperature. When the water temperature drops below a set threshold, the sensor sends a signal to the controller, which then starts the pump body. The impeller rotation drives water circulation, using frictional heat to raise the water temperature, thereby preventing the water inside the pump head from freezing and avoiding damage to the impeller and pump head due to freezing cracks or icing. However, this sensor-based antifreeze method has certain hidden dangers. Once the temperature sensor fails, the entire antifreeze measure will fail, and the pump set will face the risk of freezing cracks and damage again. Its antifreeze reliability is limited and cannot meet the strict requirements for high reliability in ancient building fire protection systems. Therefore, based on the above problems, an antifreeze booster pump set for ancient building fire protection water systems is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an antifreeze booster pump set for fire protection water systems in ancient buildings, so as to solve the problem that the existing antifreeze booster pump sets have limited reliability of antifreeze measures and are difficult to meet the high reliability requirements of fire protection systems in ancient buildings.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A freeze-proof booster pump set for a fire-fighting water system in ancient buildings includes a base and a pump set body. The pump set body is installed on the upper side of the base. A water storage section is installed on the inner side of the base. The water storage section includes an outer shell fixed to the inner side of the base. An insulation layer is fixedly connected to the inner cavity of the outer shell. A transmission pipe is connected to the left side of the outer shell, and a guide hole is connected to the right side of the outer shell. A piston plate is slidably connected to the inner side of the outer shell. A drive unit is installed at the water storage section. The drive unit includes a connecting rod located inside the guide hole. The left end of the connecting rod is fixedly connected to the right end face of the piston plate. A middle connecting bar is fixedly connected to the right end of the connecting rod. A gear rod located on the front side of the base is fixedly connected to the left side of the middle connecting bar. A rotating rod is rotatably connected to the front side of the base. A gear meshing with the gear rod is fixedly connected to the outer side of the rotating rod. A locking part is installed at the base.

[0007] Preferably, a guide rod is fixedly connected to the upper side of the housing, a limit block is fixedly connected to the upper end of the guide rod, a horizontally arranged sleeve is slidably connected to the outer side of the guide rod, a second spring is provided between the limit block and the sleeve, and the second spring is sleeved on the outer side of the guide rod, and a guide clip is fixedly connected to the lower right end of the sleeve.

[0008] Preferably, the pump assembly includes a motor fixed to the upper side of the housing, a pump head fixedly connected to the left side of the motor, an impeller fixedly connected to the end of the output shaft of the motor inside the pump head, a pressure tank connected to the pump head mounted on the upper side of the motor, a controller mounted on the upper side of the motor, a temperature sensor mounted at the right side of the pump head, and the upper end of the transmission pipe connected to the pump head.

[0009] Preferably, a spring is provided between the right end face of the outer shell and the middle connecting strip. The spring is sleeved on the outside of the connecting rod. The cross-section of the connecting rod is cross-shaped, and the length of the connecting rod is the same as the length of the inner cavity of the outer shell.

[0010] Preferably, the guide rod is a square rod structure, the guide strip is disposed on the right side of the base housing, a gap is provided between the guide strip and the base housing, the lower right end of the guide strip is provided with an arc-shaped rounded corner, and the arc-shaped rounded corner of the guide strip is set at the same height as the middle connecting strip.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the drive unit, water storage unit, and locking unit are designed to allow the drive unit to work with the water storage unit to pump water from the pump head of the pump unit when the main pump unit is stopped. This allows the water stored in the pump body to be drawn into the outer casing and insulated by the insulation layer. When the main pump unit needs to be operated, the drive unit can also return the stored water to the pump head. At this time, the locking unit can position the drive unit and piston plate to ensure that the piston plate cannot move to the right on its own. This enables the booster pump unit to operate stably and reliably in low-temperature environments through multiple anti-freezing measures, meeting the stringent high reliability requirements of ancient building fire protection systems. It effectively solves the problem that the existing anti-freezing booster pump units have limited reliability in anti-freezing measures and cannot meet the high reliability requirements of ancient building fire protection systems.

[0027] Please see Figure 1-7 This utility model provides a technical solution:

[0028] A freeze-proof booster pump set for a fire-fighting water system in ancient buildings includes a housing 1 and a pump set body 2. The pump set body 2 is installed on the upper side of the housing 1, and a water storage section 3 is installed inside the housing 1. The water storage section 3 includes an outer shell 31 fixed inside the housing 1. An insulation layer 32 is fixedly connected to the inner cavity of the outer shell 31. A transmission pipe 33 is connected to the left side of the outer shell 31, and a guide hole 34 is connected to the right side of the outer shell 31. A piston plate 35 is slidably connected to the inner side of the outer shell 31. A drive unit 4 is installed at the location. The drive unit 4 includes a connecting rod 41 located inside the guide hole 34. The left end of the connecting rod 41 is fixedly connected to the right end face of the piston plate 35. A middle connecting bar 42 is fixedly connected to the right end of the connecting rod 41. A gear 43 located on the front side of the housing 1 is fixedly connected to the left side of the middle connecting bar 42. A rotating rod 44 is rotatably connected to the front side of the housing 1. A gear 45 that meshes with the gear 43 is fixedly connected to the outer side of the rotating rod 44. A locking part 6 is installed at the housing 1.

[0029] A guide rod 61 is fixedly connected to the upper side of the housing 1. A limit block 62 is fixedly connected to the upper end of the guide rod 61. A horizontally arranged sleeve 63 is slidably connected to the outer side of the guide rod 61. A second spring 64 is provided between the limit block 62 and the sleeve 63, and the second spring 64 is sleeved on the outer side of the guide rod 61. A guide clip 65 is fixedly connected to the lower right end of the sleeve 63. The provided clip 65 can position the drive unit 4 and the piston plate 35, preventing the piston plate 35 from moving to the right on its own. The pump unit body 2 includes a guide rod 61 fixed to the upper side of the housing 1. Motor 21, pump head 23 is fixedly connected to the left side of motor 21, impeller 22 located inside pump head 23 is fixedly connected to the end of output shaft of motor 21, pressure tank 24 connected to pump head 23 is installed on the upper side of motor 21, controller 25 is installed on the upper side of motor 21, temperature sensor 26 is installed at the hole on the right side of pump head 23, upper end of transmission pipe 33 is connected to pump head 23, through this arrangement, water storage section 3 can pump water from pump head 23; spring is provided between the right end face of housing 31 and middle connecting strip 42. Spring 5 is sleeved on the outside of the connecting rod 41. Spring 5 allows the drive unit 4, after moving left, to be reset and moved right. The connecting rod 41 has a cross-shaped cross section. This design allows the rightward movement of the piston plate 35 to discharge gas from the right side of the piston plate 35 through the guide hole 34, without being restricted by the connecting rod 41. The length of the connecting rod 41 is the same as the length of the inner cavity of the outer casing 31. This design allows the piston plate 35 to be pushed to the leftmost side of the outer casing 31 by the connecting rod 41. Guide rod 61 The structure is a square rod, which allows the sleeve 63 and guide strip 65 to move vertically but not rotate. The guide strip 65 is located on the right side of the housing 1, and there is a gap between the guide strip 65 and the housing 1. This allows the middle connecting strip 42 to move to the left side of the guide strip 65. The lower right side of the guide strip 65 is rounded, and the rounded corner of the guide strip 65 is at the same height as the middle connecting strip 42. This allows the middle connecting strip 42 to press against the guide strip 65 when it moves to the left, forcing the guide strip 65 to move upward.

[0030] Workflow: In the fire-fighting water system of ancient buildings, to ensure the stable and reliable operation of the antifreeze booster pump set in low-temperature environments, this application proposes the following antifreeze measures, the specific operation of which is as follows. Please see the following description. Figure 7After the main body 2 of the pump unit is used, the firefighters need to first close the water inlet pipe of the external connection pump head 23, and then pull up the guide strip 65 of the locking part 6 to stop it from limiting the middle connecting strip 42 of the drive part 4. At this time, the spring 5 in the compressed state will push the middle connecting strip 42 to the right, thereby driving the connecting rod 41 and the piston plate 35 to move to the right. The rightward movement of the piston plate 35 draws the water stored in the pump head 23 into the outer casing 31 through the transmission pipe 33, thereby emptying the water in the pump head 23. In this way, even in a low temperature environment, since there is no water stored in the pump head 23, the water is effectively prevented from freezing, thus preventing cracking or freezing. Ice can damage the impeller 22 and pump head 23. The water pumped into the storage section 3 can be kept warm by the insulation layer 32 to prevent freezing, allowing the pump unit 2 to be used again. When the pump unit 2 is needed for firefighting operations on ancient buildings, firefighters can rotate the lever 44 to drive the gear 45. The gear 45 meshes with the rack 43, causing the rack 43, intermediate connecting bar 42, connecting rod 41, and piston plate 35 to move to the left. The leftward movement of the piston plate 35 pushes the stored water back into the pump head 23 through the connecting pipe, enabling the pump unit 2 to operate normally and perform water intake and pressurization to meet the requirements. For fire protection needs, when the middle connecting bar 42 moves to the far left, it will pass the guide bar 65. During this process, the middle connecting bar 42 will apply pressure to the guide bar 65, causing it to move upward. Subsequently, under the elastic action of the second spring 64, the guide bar 65 will return to its original position downward and lock the middle connecting bar 42, thereby completing the positioning of the drive unit 4 and the piston plate 35 and preventing the piston plate 35 from moving to the right on its own. This antifreeze measure of this application, through the design of the mechanical structure, realizes the automatic extraction and reinjection of water in the pump head 23, effectively improving the reliability of antifreeze. Of course, if the firefighter forgets to perform the above-mentioned operation of extracting water from the pump head 23, the existing base The antifreeze measures for temperature sensor 26 can still be used as a backup solution. Temperature sensor 26 can monitor water temperature in real time. When the water temperature drops below the set threshold, the pump body is automatically started. The impeller 22 drives the water flow to circulate and uses the friction heat of water to raise the water temperature, thereby ensuring the antifreeze stability of the pump body 2 in low-temperature environments. This application realizes that the booster pump group can operate stably and reliably in low-temperature environments through multiple antifreeze measures, which meets the strict requirements of high reliability for ancient building fire protection systems and effectively solves the problem that the existing antifreeze booster pump group has limited reliability and is difficult to meet the high reliability requirements of ancient building fire protection systems.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
