Description
Technical Field
[0001] This utility model is a pressurized water supply device for drinking water, belonging to the field of drinking water technology. Background Technology
[0002] Pressurized drinking water supply refers to increasing water pressure through specific equipment and technology to meet users' demands for drinking water in terms of flow and pressure. Pump pressurization is the most common method. Water is drawn from a water source or storage facility and pressurized by a pump installed on the water supply pipeline, enabling it to overcome pipeline resistance and height differences and be delivered to the user. Vertical pumps are commonly used in pressurized water supply. In actual use, two sets of vertical pumps are often required to work together. The two vertical pumps are installed between the inlet and outlet main pipes. By switching the operation of the two vertical pumps, it is convenient to repair the faulty pump without affecting the water supply. Vertical pumps require multiple screws to be mounted on the base. These screws, which restrict the position of the vertical pump, are located between the inlet and outlet main pipes, making the space for removing and installing these screws limited and increasing the difficulty of disassembling the vertical pump later. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressurized water supply device for drinking water to solve the problems mentioned in the background technology. This utility model allows the screws that restrict the vertical pump to be in an open space, reducing the difficulty of disassembling the vertical pump later.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pressurized drinking water supply device, comprising a base, two vertical pumps mounted on the upper side of the base, each of the two vertical pumps having a top plate fitted onto its impeller chamber and fixedly connected to the impeller chamber, a horizontal plate on the upper side of the top plate, and two pin holes in the area covered by the horizontal plate on the upper surface of the top plate, with pins inserted into the pin holes, the upper ends of the pins being fixedly connected to the horizontal plate, and through holes at both ends of the pins, with a straight threaded cylinder below the through holes, a semi-threaded screw threadedly connected to the lower part of the straight threaded cylinder, the lower end of the semi-threaded screw being connected to the base via an adjusting component, and a screw threadedly connected to the straight threaded cylinder being inserted into the through holes.
[0005] Furthermore, the adjusting component includes a slide block, the lower end of the semi-threaded screw is fixedly connected to the slide block, the lower end of the slide block is in contact with the base, one side of the slide block has a horizontal hole, a stud is inserted in the horizontal hole, both ends of the stud are connected to the base, and nuts that are threadedly connected to the stud are provided on both sides of the horizontal hole along the length direction of the stud.
[0006] Furthermore, each end of the stud is fitted with a lug, which is connected to the base by bolts.

[0010] Furthermore, a support is installed at the bottom of the impeller chamber of the vertical pump, and the support fits into the base.
[0011] The beneficial effects of this utility model are:
[0012] 1. Adjust the position of the slide along the stud according to the relative position of the vertical pump and the base. At this time, the relative position of the semi-threaded screw and the through hole will change. After the semi-threaded screw and the through hole are aligned, use two nuts to restrict the relative position of the stud and the slide, so as to adjust the position of the semi-threaded screw according to the position of the vertical pump.
[0013] 2. Adjust the length of the semi-threaded screw inside the straight threaded cylinder, thereby changing the height of the straight threaded cylinder. This allows for adjustment of the relative position of the straight threaded cylinder and the top plate as needed, meeting the installation requirements of top plates at different heights and expanding the scope of application.
[0014] 3. Insert the pin on the horizontal plate into the corresponding pin hole on the top plate, and then screw the screw through the through hole into the straight threaded cylinder to restrict the vertical pump on the base.

Detailed Implementation
[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a pressurized drinking water supply device, including a base 1, two vertical pumps 5 on the upper side of the base 1, a main inlet pipe 9 on one side of the base 1, the liquid inlet end of the vertical pump 5 is connected to the main inlet pipe 9, a main outlet pipe 4 on the side of the base 1 away from the main inlet pipe 9, two interconnected butterfly valves 3 installed between the main outlet pipe 4 and the liquid outlet end of the vertical pump 5, a pressure tank 2 installed on the upper surface of the base 1, the pressure tank 2 is connected to the main outlet pipe 4 through a pipe, connecting the pressure tank 2 to the main outlet pipe 4 is beneficial to maintain a certain water pressure in the main outlet pipe 4 when the vertical pump 5 stops working, a support is installed at the bottom of the impeller chamber of the vertical pump 5 so that the support fits against the base 1, increasing the contact range between the vertical pump 5 and the base 1.
[0023] See Figures 1-4Both vertical pumps 5 have a top plate 11 fixedly connected to the impeller chamber. A horizontal plate 10 is located on the upper side of the top plate 11. Two pin holes 16 are formed in the area covered by the horizontal plate 10 on the upper surface of the top plate 11. A pin 18 is inserted into each pin hole 16, and its upper end is fixedly connected to the horizontal plate 10. Both ends of the pin 18 have through holes 17. A straight threaded cylinder 7 is located below each through hole 17. Two symmetrically arranged flat surfaces for engaging wrenches are machined on the outer surface of the straight threaded cylinder 7. A half-threaded screw 8 is threaded into the lower part of the straight threaded cylinder 7. A screw 6, threaded to the straight threaded cylinder 7, is inserted into the through hole 17. The adjustment of the half-threaded screw 8... The length of the threaded screw 8 inside the straight threaded cylinder 7 changes the height of the straight threaded cylinder 7, allowing the relative position of the straight threaded cylinder 7 and the top plate 11 to be adjusted as needed to meet the installation requirements of top plates 11 at different heights, thus expanding the applicable range. The pin 18 on the horizontal plate 10 is inserted into the corresponding pin hole 16 on the top plate 11, and then the screw 6 is screwed into the straight threaded cylinder 7 through the through hole 17, thereby restricting the vertical pump 5 to the base 1. At this time, the screw 6 is not blocked by the pipes formed by the inlet main pipe 9, outlet main pipe 4, etc., so that the screw 6 restricting the vertical pump 5 is in an open space, reducing the difficulty of disassembling the vertical pump 5 later.
[0024] See Figure 1 , Figure 2 and Figure 4 The lower end of the semi-threaded screw 8 is connected and fixed to a slide block 13. The lower end of the slide block 13 fits against the base 1. A horizontal hole is opened on one side of the slide block 13, and a stud 14 is inserted into the horizontal hole. Both ends of the stud 14 are equipped with lugs 15, so that the lugs 15 are connected to the base 1 by bolts, thus completing the connection of both ends of the stud 14 to the base 1. Nuts 12 that are threaded to the stud 14 are provided on both sides of the horizontal hole along the length direction of the stud 14. According to the relative position of the vertical pump 5 and the base 1, the position of the slide block 13 is adjusted along the stud 14. At this time, the relative position of the semi-threaded screw 8 and the through hole 17 changes. When the semi-threaded screw 8 and the through hole 17 are aligned, the two nuts 12 are used to restrict the relative position of the stud 14 and the slide block 13, so as to realize the adjustment of the position of the semi-threaded screw 8 according to the position of the vertical pump 5.
