Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, specifically to a monitoring and control device for rural water supply. Background Technology

[0002] In existing technologies, agricultural irrigation uses deep well water for irrigation and submersible pumps for water supply. However, in existing technologies, the depth of the submersible pump in the water is generally determined based on experience. The probability of the submersible pump running dry is very high, which directly causes the submersible pump to burn out and directly affects production.

[0003] Application No.: CN202220117236.3 "A Monitoring and Control Device for Rural Water Supply" This device uses a liquid level detection mechanism to detect the water pump's depth in real time. When the detected water level is lower than a set level, the display controller stops the water pump, preventing it from running dry and ensuring water supply safety. The circuit shaft is controlled by a drive motor, and the display controller shows the water level in real time, making operation labor-saving. The cable end is connected to the control display via a contact mechanism, ensuring reliable electrical contact without affecting the cable retraction and unwinding operation.

[0004] However, the bottom opening of the cable tray in the aforementioned water supply monitoring and control device cannot be expanded, which makes it impossible to expand the cable tray according to wellheads of different diameters, thereby reducing the applicability of the aforementioned water supply monitoring and control device. Utility Model Content

[0005] The purpose of this invention is to provide a monitoring and control device for rural water supply that is suitable for wellheads of different diameters, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a monitoring and control device for rural water supply, comprising a control component, wherein an expandable support component is provided at the bottom of the control component, and a pumping component is attached to the bottom of the support component;

[0007] The bearing assembly includes: a bearing plate, three sets of support members on the side of the bearing plate, the top of the bearing plate being fixedly connected to the outside of the drive motor, the output shaft of the drive motor being connected to the top of the screw through a coupling, the side of the screw being threadedly connected to the inside of the moving block, the side of the moving block being rotatably connected to the bottom of the connecting rod, and the top of the connecting rod being connected to the side of the support member.

[0008] Preferably, the bottom end of the screw is fixedly connected to the top of the limiting plate, and the bottom of the limiting plate is fixedly connected to the outside of the lifting ring.

[0009] Preferably, the support member includes: a support cylinder, the top end of which is rotatably connected to the side of the bearing plate, a strip-shaped through hole is provided on one side of the support cylinder, and the other side of the support cylinder is rotatably connected to the top end of the connecting rod.

[0010] Preferably, the wall of the strip-shaped through hole is slidably connected to the outside of the lead screw, and one end of the lead screw is fixedly connected to one side of the telescopic rod.

[0011] Preferably, the external thread of the lead screw is connected to the inner ring of the locking sleeve, and the locking sleeve is located on the outside of the support cylinder.

[0012] Preferably, the telescopic rod is slidably inserted into the inside of the support cylinder, and a scale is provided on one side of the telescopic rod.

[0013] Preferably, the control component includes: a control display, the bottom of which is mounted on the top of the mounting plate, the bottom of which is fixedly connected to the top of the upright, and the bottom of which is fixedly connected to the top of the support plate.

[0014] Preferably, the pumping assembly includes a water pump, and a second lifting ring is fixedly provided on the top of the water pump. The second lifting ring and the first lifting ring are connected together by a lifting rope.

[0015] Preferably, the water pump is externally fixedly connected to the inner ring of the fixing ring, and an immersion-type liquid level sensor is installed on the fixing ring. The immersion-type liquid level sensor is electrically connected to the control display.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses a drive motor to rotate a screw. When the screw rotates clockwise, it drives a moving block to move towards a support plate. As the moving block moves towards the support plate, it pushes the support members through a connecting rod, causing the bottom ends of the three sets of support members to move away from each other and expand. When the drive motor drives the screw to rotate counterclockwise, the screw drives the moving block to move towards a limiting plate. As the moving block moves towards the limiting plate, it pulls the support members through a connecting rod, causing the bottom ends of the three sets of support members to move closer together. This allows the bottom openings of the three sets of support members to be expanded and adjusted according to well openings of different diameters, thus improving the applicability of the water supply monitoring and control device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a monitoring and control device for rural water supply, including: a control component 2, an expandable support component 1 at the bottom of the control component 2, and a pumping component 3 attached to the bottom of the support component 1.

[0027] The supporting assembly 1 includes a supporting plate 12. Three sets of support members 14 are provided on the side of the supporting plate 12. The top of the supporting plate 12 is fixedly connected to the outside of the drive motor 11. The output shaft of the drive motor 11 is connected to the top of the screw 13 via a coupling. The side of the screw 13 is threadedly connected to the inside of the moving block 16. The side of the moving block 16 is rotatably connected to the bottom of the connecting rod 15. The top of the connecting rod 15 is connected to the side of the support member 14. The bottom of the screw 13 is fixedly connected to the top of the limiting plate 17, and the bottom of the limiting plate 17 is fixedly connected to the outside of the lifting ring 18.

[0028] The drive motor 11 drives the screw 13 to rotate. When the screw 13 rotates clockwise, it drives the moving block 16 to move towards the support plate 12. As the moving block 16 moves towards the support plate 12, it pushes the support member 14 through the connecting rod 15, thereby causing the bottom ends of the three sets of support members 14 to move away from each other and expand. When the drive motor 11 drives the screw 13 to rotate counterclockwise, the screw 13 drives the moving block 16 to move towards the limiting plate 17. As the moving block 16 moves towards the limiting plate 17, it pulls the support member 14 through the connecting rod 15, thereby causing the bottom ends of the three sets of support members 14 to move closer together. This allows the bottom openings of the three sets of support members 14 to expand and adjust according to the diameter of the wellhead, making it suitable for wellheads of different diameters and improving the applicability of the water supply monitoring and control device.

[0029] The support member 14 includes a support cylinder 141, the top end of which is rotatably connected to the side of the bearing plate 12. A strip-shaped through hole 142 is provided on one side of the support cylinder 141, and the other side is rotatably connected to the top end of the connecting rod 15. The wall of the strip-shaped through hole 142 is slidably connected to the outside of a lead screw 143, one end of which is fixedly connected to one side of a telescopic rod 145. The external thread of the lead screw 143 is connected to the inner ring of a locking sleeve 144, which is located outside the support cylinder 141. The external telescopic rod 145 is slidably inserted into the inside of the support cylinder 141, and a scale is provided on one side of the telescopic rod 145.

[0030] Loosen the locking sleeve 144, then push the locking sleeve 144. The locking sleeve 144, in turn, drives the telescopic rod 145 through the lead screw 143, thereby allowing the telescopic rod 145 to extend from the support cylinder 141 to accommodate wellheads of larger diameters. The scale on the outside of the telescopic rod 145 facilitates control of its extension length. Once the telescopic rod 145 has extended to the appropriate length, tighten the locking sleeve 144.

[0031] The control assembly 2 includes a control display 21, the bottom of which is mounted on the top of the mounting plate 22. The bottom of the mounting plate 22 is fixedly connected to the top of the upright 23, and the bottom of the upright 23 is fixedly connected to the top of the support plate 12.

[0032] The pumping assembly 3 includes a water pump 34. A second lifting ring 32 is fixedly mounted on the top of the water pump 34. The second lifting ring 32 and the first lifting ring 18 are connected together by a lifting rope 31. The water pump 34 is externally fixedly connected to the inner ring of a fixing ring 35. A submersible liquid level sensor 33 is mounted on the fixing ring 35. The submersible liquid level sensor 33 is electrically connected to the control display 21.

[0033] When the liquid level detected by the submersible level sensor 33 is lower than the set value, the submersible level sensor 33 will transmit a signal to the control display 21, and the control display 21 will disconnect the power supply to the water pump 34. Controlling the water pump 34 using a level sensor is existing technology, and the structure of the display controller will not be described in detail here.

[0034] The working principle of this utility model is as follows: the drive motor 11 drives the screw 13 to rotate. When the screw 13 rotates clockwise, it drives the moving block 16 to move towards the bearing plate 12. At the same time, the moving block 16 pushes the support member 14 through the connecting rod 15, thereby causing the bottom ends of the three sets of support members 14 to move away from each other and expand. When the drive motor 11 drives the screw 13 to rotate counterclockwise, the screw 13 drives the moving block 16 to move towards the limiting plate 17. At the same time, the moving block 16 pulls the support member 14 through the connecting rod 15, thereby causing the bottom ends of the three sets of support members 14 to move closer together. In this way, the bottom openings of the three sets of support members 14 can be expanded and adjusted according to the wellheads of different diameters to be suitable for wellheads of different diameters, thus improving the applicability of the water supply monitoring and control device.

[0035] Simultaneously, the locking sleeve 144 can be loosened, and then pushed. The locking sleeve 144, in turn, drives the telescopic rod 145 through the lead screw 143, thereby allowing the telescopic rod 145 to extend from the support cylinder 141, making it suitable for wellheads with larger diameters. The scale on the outside of the telescopic rod 145 facilitates control of the extension length of the telescopic rod 145. After the telescopic rod 145 has extended to the appropriate length, the locking sleeve 144 is tightened.

[0036] 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.
