Description

Technical Field

[0001] The utility model relates to the technical field of variable-frequency pumps, in particular to a vehicle-mounted foam liquid variable-frequency pump. Background Art

[0002] A variable-frequency pump is a pump that uses variable-frequency technology to control the rotational speed of an electric motor. The main feature of this pump is its ability to dynamically adjust the flow rate and pressure according to the system's requirements, thereby improving the energy efficiency and operating stability of the system. Variable-frequency pumps are widely used in many fields such as agricultural irrigation and fire extinguishing, especially in water treatment and water supply technologies.

[0003] Variable-frequency pumps in the prior art generally include a variable-frequency pump body, a variable-frequency motor, and a controller. The variable-frequency motor can be controlled by the controller, and then the variable-frequency pump body can be controlled to achieve an energy-saving effect. Most of the variable-frequency pumps mounted on fire trucks are directly fixed on the fire truck through a mounting frame or a mounting base. During operation, they will generate relatively large noise and vibration, which leads to problems such as noise pollution and internal parts of the vehicle-mounted variable-frequency pump being easily damaged due to vibration when in use. At the same time, after long-term use of the current variable-frequency pump, problems such as overheating inside the pump, resulting in the pump being unable to work, will occur.

[0004] In the utility model with the application number: CN201620282208.1 and the publication number: CN205478154U, an intelligent constant-pressure variable-frequency pump is disclosed. It is characterized in that it includes a pump body, a frequency converter, and a heat dissipation device. The pump body is provided with a motor, the heat dissipation device is arranged on the motor, and a first heat dissipation fin in contact with the motor is provided on the side of the heat dissipation device opposite to the motor. The frequency converter is arranged on the heat dissipation device. Although it can solve the problem of the variable-frequency pump not being able to work due to internal overheating, it still has problems such as noise pollution and internal parts of the variable-frequency pump being easily damaged due to vibration.

Detailed implementation mode

[0028] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0029] Embodiment:

[0030] As Figures 1 to 3 shown, to solve the above problems, this embodiment discloses a vehicle - mounted foam liquid variable - frequency pump, which includes a variable - frequency pump body 10, a variable - frequency motor 20, a controller 30 and a shock - absorbing mounting assembly 40. The variable - frequency pump body 10, the variable - frequency motor 20 and the controller 30 are cooperatively installed on the shock - absorbing mounting assembly 40. The variable - frequency motor 20 is located on one side of the variable - frequency pump body 10 and is connected to the variable - frequency pump body 10 for driving the variable - frequency pump body 10;

[0031] The shock - absorbing mounting assembly 40 includes a first mounting table 400, a second mounting table 401, a mounting base 402 and four damping shock absorbers 403. The first mounting table 400 and the second mounting table 401 are fixedly arranged on the mounting base 402, and the second mounting table 401 is located on one side of the first mounting table 400. The four damping shock absorbers 403 are cooperatively arranged at the bottom of the mounting base 402 and are detachably connected to the mounting base 402. The four damping shock absorbers 403 can be detachably connected to a fire truck;

[0032] The variable - frequency pump body 10 is arranged on the first mounting table 400, the variable - frequency motor 20 is arranged on the second mounting table 401, and the controller 30 is arranged on one side of the mounting base 402.

[0033] When the utility model is in use, through the setting of four damping shock absorbers 403, the vibration and noise generated during the operation of the variable-frequency pump main body 10 and the variable-frequency motor 20 can be effectively reduced. Compared with the prior art, the utility model can effectively protect the variable-frequency pump main body 10 and the variable-frequency motor 20, thus solving the problems of noise pollution and the internal parts of the variable-frequency pump being easily damaged due to vibration during the use of the current fire truck-mounted variable-frequency pump.

[0034] Meanwhile, the installation base 402 is detachably connected to the fire truck through four damping shock absorbers 403. During the fire truck's emergency response process, if there are situations such as bumps caused by uneven road surfaces, it can also play a certain role in damping and protecting the variable-frequency pump main body 10 and the variable-frequency motor 20, thus solving the problem of the internal parts of the variable-frequency pump being damaged due to vehicle vibration during transportation.

[0035] The variable-frequency pump main body 10, the variable-frequency motor 20, and the controller 30 can adopt a foam liquid variable-frequency pump that can achieve the functions of the utility model in the prior art.

[0036] The damping shock absorber 403 can adopt a damping shock absorber 403 that can achieve the functions of the utility model in the prior art.

[0037] As Figure 4 shown, in order to better achieve the damping function, in this embodiment, a specific structure of the damping shock absorber 403 is provided. The damping shock absorber 403 includes a bottom mounting seat 404, a fixed sleeve 405, a sliding sleeve 406, a spring 407, a damping telescopic rod 408, and a connecting screw 409. The bottom mounting seat 404 can be detachably connected to the fire truck through bolts. The fixed sleeve 405 is arranged on the bottom mounting seat 404 and is fixedly connected to the bottom mounting seat 404. The sliding sleeve 406 is arranged outside the fixed sleeve 405, and the inner side wall of the sliding sleeve 406 is slidably connected to the outer side wall of the fixed sleeve 405. An installation cavity 410 is provided inside the fixed sleeve 405 and the sliding sleeve 406. The spring 407 and the damping telescopic rod 408 are arranged in the installation cavity 410. One end of the damping telescopic rod 408 is fixedly connected to the fixed sleeve 405, and the other end is fixedly connected to the sliding sleeve 406. The spring 407 is sleeved outside the damping telescopic rod 408 and can respectively contact the fixed sleeve 405 and the sliding sleeve 406 at both ends. The connecting screw 409 is fixedly arranged on the top of the sliding sleeve 406. A threaded hole 411 that cooperates with the connecting screw 409 is provided on the installation base 402. The connecting screw 409 can be detachably connected to the installation base 402 through the threaded hole 411.

[0038] During use, the damping effect can be generated through the cooperation between the spring 407, the damping telescopic rod 408, the fixed sleeve 405, and the sliding sleeve 406. Among them, mainly through the cooperation between the damping telescopic rod 408 and the spring 407, the kinetic energy of the vibration is converted into heat energy generated by friction, so as to achieve the damping effect.

[0039] Among them, an anti-slip pad 412 is provided at the bottom of the bottom mounting seat 404, and a mounting groove 413 is provided on the bottom mounting seat 404 and is arranged in cooperation with the anti-slip pad 412. One end of the anti-slip pad 412 is arranged in the mounting groove 413 and is fixedly connected to the mounting groove 413, and the other end can be in contact with the fire truck.

[0040] The anti-slip pad 412 can adopt the anti-slip pad 412 in the prior art that can realize the functions of the present utility model, such as the anti-slip pad 412 made of rubber material.

[0041] The setting of the anti-slip pad 412 can make the connection between the damping shock absorber 403 and the fire truck more stable, and at the same time can play a role in preventing the bolts from loosening to a certain extent.

[0042] The damping telescopic rod 408 can adopt the damping telescopic rod 408 in the prior art that can realize the functions of the present utility model, or the following structure of the damping telescopic rod 408 can also be adopted.

[0043] The damping telescopic rod 408 includes a damping rod 414 and a damping sleeve 415. One end of the damping sleeve 415 is fixedly connected to the fixed sleeve 405. One end of the damping rod 414 is arranged in the damping sleeve 415 and is slidably connected to the damping sleeve 415. The other end of the damping rod 414 is fixedly connected to the sliding sleeve 406. There is damping between the outer side wall of the damping rod 414 and the inner side wall of the damping sleeve 415.

[0044] There is damping between the outer side wall of the damping rod 414 and the inner side wall of the damping sleeve 415, that is, there is friction between the outer side wall of the damping rod 414 and the inner side wall of the damping sleeve 415. Thus, when the damping rod 414 moves in the damping sleeve 415, the kinetic energy of the vibration is converted into heat energy generated by friction, so as to cooperate with the spring 407 to achieve the damping effect.

[0045] As Figure 4 shown, in order to further improve the damping effect, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a rubber ring 416 is provided on the inner side wall of the sliding sleeve 406 and is arranged in cooperation with the outer side wall of the fixed sleeve 405. The rubber ring 416 is fixedly arranged on the inner side wall of the sliding sleeve 406 and is slidably connected to the outer side wall of the fixed sleeve 405.

[0046] There is also a certain amount of friction between the rubber ring 416 and the outer side wall of the fixed sleeve 405. Thus, when the sliding sleeve 406 and the fixed sleeve 405 move relative to each other, a part of the kinetic energy of the vibration can also be converted into heat energy generated by friction, so as to achieve a certain damping effect.

[0047] As Figure 2 、 Figure 5As shown, in order to further improve the damping effect, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the mounting base 402 includes an upper clamping plate 417, a rubber damping pad 418, a lower clamping plate 419 and a first side plate 420. The rubber damping pad 418 is arranged between the upper clamping plate 417 and the lower clamping plate 419. The upper clamping plate 417 and the lower clamping plate 419 are detachably connected by bolts. The first side plate 420 is arranged on one side of the upper clamping plate 417 and is fixedly connected to the upper clamping plate 417. The first mounting table 400 and the second mounting table 401 are fixedly arranged on the upper clamping plate 417. The threaded holes 411 are arranged on the lower clamping plate 419. The connecting screws 409 of the four damping shock absorbers 403 are detachably connected to the lower clamping plate 419 through the threaded holes 411. The controller 30 is arranged on the first side plate 420.

[0048] The setting of the rubber damping pad 418 can absorb part of the kinetic energy generated by vibration, thus playing a damping effect to a certain extent. The setting of the upper clamping plate 417 can facilitate the installation of the first mounting table 400 and the second mounting table 401. The setting of the lower clamping plate 419 can facilitate the installation of the damping shock absorbers 403.

[0049] Preferably, a connecting nut 428 is arranged at the bottom of the lower clamping plate 419 and is arranged in cooperation with the threaded hole 411. The connecting nut 428 is fixedly arranged on the lower clamping plate, and the connecting screw 409 is threadedly connected to the connecting nut 428.

[0050] The setting of the connecting nut 428 can make the connection between the connecting screw 409 and the lower clamping plate 419 more stable.

[0051] As Figure 5 shown, in order to facilitate the installation of the controller 30, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a control box 421 for installing the controller 30 is arranged on one side of the first side plate 420. The control box 421 and the first side plate 420 are detachably connected by bolts. The controller 30 is arranged in the control box 421. Threading holes 422 for wire routing are arranged on the first side plate 420 and the control box 421.

[0052] As Figure 5 shown, in order to facilitate the cooling of the variable frequency motor 20, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a second side plate 423 is arranged at the top of the first side plate 420. A heat dissipation component 424 is arranged on the second side plate 423. The heat dissipation component 424 is arranged in cooperation with the variable frequency motor 20 and is detachably connected to the second side plate 423.

[0053] Among them, an installation window 425 is provided on the second side plate 423. The heat dissipation assembly 424 includes an installation frame body 426 and a heat dissipation fan 427. The installation frame body 426 is arranged on the second side plate 423 and is cooperatively arranged with the installation window 425. The heat dissipation fan 427 is arranged inside the installation frame body 426 and is cooperatively arranged with the installation window 425.

[0054] The installation frame body 426 and the second side plate 423 are detachably connected by bolts.

[0055] During use, the variable frequency motor 20 can be cooled by the heat dissipation fan 427. The settings of the second side plate 423 and the installation frame body 426 facilitate the installation of the heat dissipation fan 427.

[0056] The working principle of the present utility model:

[0057] When the present utility model is in use, through the setting of the four damping shock absorbers 403, the vibration and noise generated during the operation of the variable frequency pump main body 10 and the variable frequency motor 20 can be effectively reduced.
