[0001] The invention relates to the technical field of water pumps, in particular to a vertical mud pump capable of monitoring and regulating internal pump pressure. Background Art

[0002] A water pump is a device for pumping liquid materials. Depending on the object it acts on, the internal structure design and name of the water pump are different. A mud pump is a type of water pump.

[0003] 1. The patent name disclosed in the announcement number "CN204900308U" is "A suspended self-stirring vertical mud pump". A suspension device is arranged under the motor, so that the motor of the vertical mud pump can always be suspended above the liquid surface, without using ropes and other equipment to hang the vertical mud pump. In this way, the vertical mud pump can automatically adjust the height according to the water level, avoiding the cumbersome steps of lowering the vertical mud pump. However, the volume of the suspension device in the mud pump itself will take up a large space, which is inconvenient for the later carrying and transportation of the entire mud pump;

[0004] 2. The internal pump pressure of the mud pump is unstable during use. When the pressure inside the pump is low, the flow rate will be low, which will affect the subsequent use of the pump;

[0005] Therefore, we propose a vertical mud pump that can monitor and regulate the internal pump pressure in order to solve the above-mentioned problems. Summary of the invention

[0021] Preferably, the front and rear sides of the installation frame are internally slotted with bearings connected to threaded rods, the top of the threaded rod inside the rear side of the installation frame is connected to the rotating rod, and the lower end of the rotating rod passes through the upper surface of the installation frame.

[0022] Through the arrangement of the above structure, the rotation of the rotating rod drives one of the threaded rods to rotate, and then the two threaded rods can rotate simultaneously through the sprocket mechanism.

[0023] Preferably, an outer side of the threaded rod is threadably connected to a regulating rod, and an upper snap mechanism is fixed to the bottom end of the regulating rod.

The specific contents are as follows:

[0034] (1) A suspension airbag is provided, and the deflated suspension airbag is rolled up by installing the shaft rod b, thereby reducing the occupied area of ​​the suspension airbag. Therefore, the entire vertical mud pump can be used in a suspended state or not, thereby increasing the use range of the entire mud pump.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figure 1-9 The present invention provides a technical solution: a vertical mud pump capable of monitoring and regulating the internal pump pressure, comprising a protective shell 1 having a cylindrical structure, and the upper outer side of the protective shell 1 is threadedly connected with a locking cover 8 of an inverted "U" shape structure, and the inner side wall of the lower end of the locking cover 8 is arranged to fit the outer side of a support frame 13, as shown in the attached Figure 1 As shown in the figure, move the entire mud pump to the working area. After reaching the working area, when it is not necessary to suspend it for use, Figure 1-3 and attached Figure 7 As shown, the locking cover 8 is first rotated so that the locking cover 8 moves upward while rotating, and a torsion spring 111 is nested and connected to the outside of one end of the mounting shaft a11, and one end of the torsion spring 111 is connected to the mounting shaft a11, and the other end of the torsion spring 111 is connected to the support frame 13. At this time, the mounting shaft a11 is reversely rotated by the stored force of the torsion spring 111, and then the mounting shaft a11 drives the mounting frame 9 to reversely rotate and be in a tilted state, as shown in the attached figure. Figure 7 As shown, when the bottom end of the mounting frame 9 is in contact with the side wall of the working area, the rotation of the locking cover 8 is stopped, and then the entire mud pump can be auxiliary supported by the mounting frame 9 in an inclined state, thereby improving the stability of the entire mud pump when placed vertically in the later stage;

[0050] When it is necessary to suspend in the river, it is as shown above. Similarly, as shown in the attached Figure 1-3 As shown, the locking cover 8 is rotated upward so that the locking cover 8 rotates and moves upward at the same time. When the locking cover 8 rises to a certain position and has no limiting blocking effect on the mounting frame 9, the mounting shaft a11 is reversely rotated by the stored force of the torsion spring 111, and then the mounting shaft a11 drives the mounting frame 9 to reversely rotate to a horizontal state. The internal bearing of the mounting frame 9 is connected to the mounting shaft b12, and the outer side of the mounting shaft b12 is sequentially wound and connected with the connecting belt 15 and the suspension airbag 10, and the lower end of the connecting belt 15 is fixedly connected to the upper end of the suspension airbag 10, as shown in the attached figure. Figure 4As shown, the lower end of the suspension airbag 10 is manually pulled to pull the suspension airbag 10 out of the installation frame 9. When the installation frame 9 is pulled out, the installation shaft b12 is driven to rotate. Then, the air is inflated into the suspension airbag 10 through the air port at the bottom of the suspension airbag 10 by an external air pumping device, and then the suspension airbag 10 is made as shown in the attached figure. Figure 3 and attached Figure 8 As shown, the bottom end of the suspension airbag 10 is equipped with an air port for exhaust and intake, and the vertical center line of the suspension airbag 10 after deployment coincides with the vertical center line of the mounting shaft b12;

[0051] The front and rear sides of the mounting frame 9 are both grooved with bearings connected to threaded rods 17, and the top of the threaded rod 17 inside the rear side of the mounting frame 9 is connected to the rotating rod 18, and the lower end of the rotating rod 18 passes through the upper surface of the mounting frame 9, and then as shown in the attached Figure 8-9 As shown, the staff manually rotates the rotating rod 18, and a sprocket mechanism 21 is provided inside the upper end of the mounting frame 9. The upper ends of the two threaded rods 17 are connected by the sprocket mechanism 21 to form a transmission connection. The rotating rod 18 drives the threaded rod 17 fixedly connected at the bottom to rotate. At the same time, the sprocket mechanism 21 is provided to make the other threaded rod 17 also rotate, and then the two threaded rods 17 rotate at the same time. When the threaded rod 17 rotates, the regulating rod 16 connected to the outer thread is driven to descend. The outer thread of the threaded rod 17 is connected to the regulating rod 16, and the regulating rod 1 An upper snap mechanism 20 is fixed at the bottom end of the control rod 16, and two lower snap mechanisms 19 are symmetrically installed on the upper surface of the suspension airbag 10, and the upper part of the lower snap mechanism 19 is connected with the upper snap mechanism 20 by concave-convex matching, so that the control rod 16 drives the upper snap mechanism 20 at the bottom to descend and perform concave-convex matching with the corresponding lower snap mechanism 19 below, so as to facilitate the fixing of the suspension airbag 10, so that the suspension airbag 10 is stably located directly below the installation frame 9, which is convenient for the suspension airbag 10 to perform a good suspension operation on the entire device, thereby improving the stability of the suspension operation;

[0052] Then the whole mud pump starts to work. Figure 1 and attached Figure 5-6As shown, the left end of the motor above the discharge pipe 5 is electrically connected to the control module, and the left end of the control module is electrically connected to the pressure sensor 14, and the detection probe of the pressure sensor 14 penetrates the upper surface of the discharge pipe 5 to perform detection work, and the pressure sensor 14 detects the pump pressure inside the discharge pipe 5 in real time. When the pressure sensor 14 detects that the pump pressure in the discharge pipe 5 is small, the pressure sensor 14 transmits this signal to the control module on the right, and the control module controls the motor on the right to start, so that the output end of the motor drives the baffle 6 below to rotate, and the outer side of the baffle 6 is closely connected to the inner wall of the discharge pipe 5, and The baffle 6 is set in a circular structure, so that the gap between the baffle 6 and the discharge pipe 5 becomes larger, which makes it easier to adjust the opening degree of the discharge pipe 5, so as to adjust the pump pressure. When the pump pressure in the entire mud pump is relatively large, as shown above, the baffle 6 is rotated in the same way to reduce the gap between the baffle 6 and the discharge pipe 5, so that it is easy to adjust well. The discharge pipe 5 is connected to the right side of the fixed shell 2, and the lower bracket 4 is installed at the bottom of the fixed shell 2. The baffle 6 is fitted inside the discharge pipe 5, and the output end of the motor above the discharge pipe 5 passes through the upper surface of the discharge pipe 5 and is connected to the upper end of the baffle 6.

[0053] When the suspension airbag 10 needs to be rolled up and placed later, as shown above, the lower snap mechanism 19 and the upper snap mechanism 20 are separated first, and then Figure 8 As shown, the air port at the bottom of the suspension airbag 10 is opened to discharge the gas inside the suspension airbag 10, and then the volume of the suspension airbag 10 becomes smaller and becomes deflated, so that the front and rear sides of the suspension airbag 10 are close to each other inward, and then the outer end of the installation shaft rod b12 is manually rotated, so that the installation shaft rod b12 rotates while winding the connecting belt 15 and the suspension airbag 10 for placement, so that the suspension airbag 10 is stored in the installation frame 9 for placement, and then the installation frame 9 is rotated to a vertical state, at this time, the installation frame 9 drives the installation shaft rod a11 to rotate, so that the torsion spring 111 accumulates force, and then the locking cover 8 is rotated, so that the locking cover 8 rotates and moves downward, and then the locking cover 8 is lowered to cover the outer side of the support frame 13, so as to prevent the installation frame 9 from rotating in the opposite direction, and then it is convenient for the installation frame 9 to be placed in a vertical state, thereby greatly reducing the occupied area;

[0054] A protective shell 1, and a fixed shell 2 installed below the protective shell 1, and an impeller 3 is arranged inside the fixed shell 2;

[0055] An upper bracket 7 is fixed to the top of the protective shell 1, and support frames 13 are installed on the left and right sides of the upper end of the protective shell 1; wherein, the internal bearing of the support frame 13 is connected to the mounting shaft a11, and the mounting frame 9 is fixed through the outer side of the middle part of the mounting shaft a11; the regulating rod 16 forms a lifting structure with the mounting frame 9 through the threaded rod 17, and the regulating rod 16 and the threaded rod 17 are arranged in a one-to-one correspondence.

[0056] The working principle of this embodiment is as follows: when using the vertical mud pump capable of monitoring and regulating the internal pump pressure, when suspension is not required, the locking cover 8 is first rotated, and then the mounting shaft a11 drives the mounting frame 9 to rotate in the opposite direction to be in an inclined state, and then the entire mud pump can be auxiliary supported by the mounting frame 9 in an inclined state;

[0057] When it is necessary to suspend the vehicle in the river, the locking cover 8 is rotated upward, so that the mounting shaft a11 drives the mounting frame 9 to rotate in the opposite direction to a horizontal state, and then the lower end of the suspension airbag 10 is manually pulled;

[0058] The staff manually rotates the rotating rod 18, so that the regulating rod 16 drives the upper snap mechanism 20 at the bottom to descend and cooperate with the corresponding lower snap mechanism 19 below;

[0059] The pressure sensor 14 detects the pump pressure inside the discharge pipe 5 in real time, and the output end of the motor drives the baffle 6 below to rotate, so it is easy to control;

[0060] When the suspension airbag 10 needs to be rolled up and placed later, the mounting shaft b12 is rotated while winding and placing the connecting belt 15 and the suspension airbag 10, thereby reducing the occupied area well and completing a series of tasks.
