Description

No negative pressure water supply installation convenient to remove

Technical Field

The utility model relates to a no negative pressure water supply technical field, concretely relates to no negative pressure water supply installation convenient to remove.

Background

The non-negative pressure water supply device takes a municipal pipe network as a water source, fully utilizes the original pressure of the municipal pipe network, forms a closed continuous relay pressurization water supply mode, has good energy-saving effect, does not have secondary pollution of water quality, and is the development and extension of variable-frequency constant-pressure water supply equipment. The non-negative pressure water supply mainly comprises a non-negative pressure steady flow tank, a pressure tank (a diaphragm type or an air bag type expansion tank), a non-negative pressure control cabinet, a water pump, a motor, a filter, a backflow preventer, a sensor, an electric contact pressure gauge, a pipeline assembly and a base for bearing the above components.

The existing non-negative pressure water supply device has the following problems during installation: generally, a non-negative pressure water supply apparatus includes an inlet pipe for connection to a municipal pipe network and an outlet pipe for connection to a user water pipe network. The existing non-negative pressure water supply device is also installed in two forms, one is to transport each part to the site and then install the part on the site, the other is to directly install the part on the base at the manufacturer and then transport the whole part to the site, and then simply butt-joint the pipelines on the site. The second installation mode is a current popular mode, and the main reason is that a manufacturer can carry out integral inspection and debugging of equipment in advance due to the fact that the equipment is installed in advance, and if a problem exists, a part can be replaced on the spot, and technicians can carry out treatment. If the installation is on the scene, if debug after the equipment and find the problem, need to change the part can waste more time, efficiency is lower. And adopt the second mode, the equipment is whole transports the scene after, only need the water pipe workman will correspond the pipeline butt joint can. If the first mode is adopted, then the technical installation workers of manufacturers are required to go to the site to install the equipment, so that the labor cost is high.

However, the second mode of installation in advance and integral transportation is adopted, which causes some problems that transportation vehicles cannot directly enter an installation site due to environmental restrictions on a plurality of sites, and the transportation is troublesome. Even if the non-negative pressure water supply device can be transported to the site by using the transportation equipment, the position is completely proper when the non-negative pressure water supply device is put down, so that the position of the non-negative pressure water supply device generally needs to be adjusted slightly.

Different from the prior art, is the structure of base, the utility model discloses in, be equipped with the removal wheel 6 that can stretch out or hold in the base on the base.

Specifically speaking, the base comprises a base body supporting frame 1, a moving wheel 6, a transmission mechanism, a lifting device and a driving mechanism.

In this embodiment, the bottom of the two sides of the main supporting frame 1 is provided with an accommodating groove 2. The lifting device comprises a lifting screw rod 5, a limiting block 4, a movable wheel 6 mounting bracket and a lifting nut 11.

Specifically speaking, 5 tops of lifting screw are equipped with

stopper

4, and 5 bottoms of lifting screw are equipped with and remove 6 installing supports of wheel, remove that wheel 6 is rotatable to be installed on removing 6 installing supports of wheel. The top of the lifting nut 11 is rotatably fixed in the accommodating groove 2 through an annular support, and the lifting screw 5 penetrates through the lifting nut 11 and is meshed with the lifting nut 11. In this embodiment, stopper 4 is square stopper 4, still is equipped with opening spacing groove 3 down at the 2 tank bottoms of holding tank, and spacing groove 3 is located 11 tops of lifting nut. Spacing groove 3 and structure and size match with stopper 4, and 3 open-ended sizes in spacing groove are less than stopper 4 for stopper 4 can't break away from in the spacing groove 3. Because stopper 4 is square, spacing groove 3 and structure and size and stopper 4 match, consequently, lifting screw 5 is unable rotatory. The mounting rack of the moving wheel 6 at the bottom of the lifting screw 5 limits the lifting screw 5 from being separated from the lifting nut 11.

The driving mechanism is used for driving the lifting device to lift, and specifically, the driving mechanism comprises a main shaft 12 rotatably arranged in a main body supporting frame 1, a bevel gear A10 is arranged on the main shaft 12, the front end of the main shaft 12 extends out of the main body supporting frame 1, and is connected with a rotating handle 15 or the front end of the main shaft 12 is provided with a motor shaft connecting hole for being detachably connected with a motor.
