A water delivery pipe 4 is fixed to the output end of the water pump 2. The water delivery pipe 4 penetrates into the interior of the mobile vehicle body 1 and extends to the outside of the mobile vehicle body 1.

[0025] In this implementation: The existing device {Publication (Announcement) Number}: CN219935620 discloses an injection test device for geological exploration of water conservancy and hydropower projects. Regarding this existing main body, this application makes further improvements. For details, refer to the disclosed technology below. To solve the technical problems existing in this existing technology, as disclosed in the background technology above, "When this above-mentioned design is in use, although it is convenient to move and carry the entire test box and ensures the overall stability of the injection pipe during the injection process, since this device is designed as an integral structure, when injection is required, this device must be moved to the injection position, and there are drilling equipment passing through or placed in the injection area, which is easily blocked, thus affecting the difficulty of moving the device to the injection area, resulting in poor use effects and being difficult to change according to actual usage requirements, reducing the use effect of the device." In combination with the use, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a telescopic component 5 is added to this application document. All the power equipment involved in this product is powered by an external power supply.

[0026] Furthermore:

[0027] As Figures 1-4 shown:

[0028] A telescopic component 5 is installed on the mobile vehicle body 1. The telescopic component 5 includes a connecting plate 501 arranged on one side of the mobile vehicle body 1, multiple sets of sleeves 503 sleeved with each other and fixed to the connecting plate 501 through a strip-shaped plate, and a mounting block 505 fixed to one end of the innermost sleeve 503. A drain elbow 506 is installed on the surface of the mounting block 505. A locking bolt 504 is fixed to the surface of each set of sleeves 503. A U-shaped frame 512 is fixed to one side of the mobile vehicle body 1 surface close to the water delivery pipe 4. A winding wheel 513 is arranged inside the U-shaped frame 512. One end of the winding wheel 513 is rotatably connected through a bearing to a universal rotary joint 511. A hose 514 is wound around the surface of the winding wheel 513;

[0029] The surface of the universal rotary joint 511 is fixedly connected to the U-shaped frame 512, and one end of the universal rotary joint 511 is fixedly connected to one end of the water delivery pipe 4. The other end of the winding wheel 513 is rotatably connected to the U-shaped frame 512 through a rotating shaft. One end of the hose 514 is fixedly connected to the universal rotary joint 511, and the other end of the hose 514 is fixedly connected to the drain elbow 506.

[0030] In this implementation: When the water injection test device for hydrogeological exploration of water conservancy and hydropower projects is in use, the mobile vehicle body 1 is pushed to move to the geological exploration water injection area. When there is no equipment obstruction to the movement of the mobile vehicle body 1 in the geological exploration water injection area, the water pump 2 is started, and then the water inside the water tank 3 is pumped out and discharged into the inside of the water delivery pipe 4, so that the water inside the water delivery pipe 4 is discharged into the hose 514, and the water inside the hose 514 is discharged into the water injection hole through the drainage elbow 506. When the geological exploration water injection area is obstructed by equipment and affects the movement of the mobile vehicle body 1, the sleeve 503 is pulled to extend, and the mounting block 505 is driven to move. The drainage elbow 506 is driven to move through the mounting block 505, and the hose 514 is pulled through the drainage elbow 506. At this time, the hose 514 drives the winding wheel 513 to rotate, so as to release the hose 514 until the drainage elbow 506 corresponds to the water injection hole. Then, the locking bolt 504 is rotated to lock the position of the sleeve 503, increasing the stability of the drainage elbow 506. Then, the water pump 2 is started to pump out the water inside the water tank 3 and discharge it into the inside of the water delivery pipe 4. The water delivery pipe 4 is discharged into the hose 514 through the universal rotary joint 511 and discharged along the drainage elbow 506. Through this operation, the problem that it is inconvenient to inject water due to equipment obstruction in the water injection area affecting the movement of the mobile vehicle body 1 is solved, so that the water injection situation can be flexibly changed more according to the actual use situation. Under the action of the sleeve 503, the stability of the drainage elbow 506 can be increased, and the water level detection will not be affected by the shaking of the drainage elbow 506, further improving the use effect of the device, being simple and convenient, meeting the actual use requirements, and avoiding the situation of the hose 514 being wound.

[0031] It should be noted that: A water level sensor is also installed on the drainage elbow 506, which can detect the water level.

[0032] Furthermore;

[0033] In an alternative embodiment, each group of sleeves 503 is designed in a frustum of a cone structure.

[0034] In this embodiment: The sleeve 503 is in the shape of a frustum of a cone, so that the situation of detachment between the two groups can be avoided, further improving the use effect of the device.

[0035] Furthermore;

[0036] In an alternative embodiment, a flow meter 507 is installed inside the drainage elbow 506.

[0037] In this embodiment: During the process of water being discharged through the drain elbow 506, the water discharge amount is detected in real time by the flow meter 507. Since the flow meter 507 is installed on the drain elbow 506, the water discharge amount can be accurately measured, avoiding the influence of the water remaining inside the hose 514 on the accuracy of the water discharge amount.

[0038] Furthermore;

[0039] In an alternative embodiment, on one side of the surface of the mobile vehicle body 1 close to the connecting plate 501, symmetrically arranged slide rails 502 are fixed. The connecting plate 501 and the mobile vehicle body 1 are connected by two sets of slide rails 502. A latch 509 is slidably connected inside the connecting plate 501. A spring 510 is wound around the surface of the latch 509. The two ends of the spring 510 are respectively fixedly connected to the latch 509 and the connecting plate 501. A lock hole 508 adapted to the latch 509 is formed on the surface of the mobile vehicle body 1;

[0040] The latch 509 is inserted into one of the lock holes 508. A through hole adapted to the latch 509 is formed on the surface of the connecting plate 501. The latch 509 and the connecting plate 501 are slidably connected through this through hole.

[0041] In this embodiment: When the drain elbow 506 corresponds to the water injection hole, the latch 509 is pulled out from one of the lock holes 508, and at the same time the spring 510 is stretched. Subsequently, the connecting plate 501 is moved, so that the connecting plate 501 moves on the surface of the mobile vehicle body 1 through the slide rails 502. Through the movement of the connecting plate 501, the drain elbow 506 can be driven to move. When the drain elbow 506 moves into the water injection hole, at this time the spring 510 rebounds and drives the latch 509 to insert into the lock hole 508 to complete the position locking of the connecting plate 501 and the drain elbow 506. By moving the drain elbow 506 to the water injection hole, it can effectively avoid the splashing of the discharged water outside the water injection hole in a strong wind environment, and can also realize the detection of the water level, further improving the use effect of the device.

[0042] Working principle and usage process of the present utility model: When using the water injection test device for geological exploration of water conservancy and hydropower projects, by pushing the mobile vehicle body 1 to move to the geological exploration water injection area. When there is no equipment obstruction to the movement of the mobile vehicle body 1 in the geological exploration water injection area, start the water pump 2, then pump out the water inside the water tank 3 and discharge it into the interior of the water delivery pipe 4, so that the water inside the water delivery pipe 4 is discharged into the flexible hose 514, and the water inside the flexible hose 514 is discharged into the water injection hole through the drainage elbow 506. When the geological exploration water injection area is obstructed by equipment, affecting the movement of the mobile vehicle body 1, pull the sleeve 503 to extend it, and drive the mounting block 505 to move. The mounting block 505 drives the drainage elbow 506 to move, and the drainage elbow 506 drives the flexible hose 514 to be pulled. At this time, the flexible hose 514 drives the winding wheel 513 to rotate, so as to release the flexible hose 514. Until the drainage elbow 506 corresponds to the water injection hole, then rotate the locking bolt 504 to lock the position of the sleeve 503, increasing the stability of the drainage elbow 506. Then start the water pump 2, pump out the water inside the water tank 3 and discharge it into the interior of the water delivery pipe 4. The water delivery pipe 4 discharges water into the flexible hose 514 through the universal rotary joint 511 and drains down along the drainage elbow 506. Through this operation, the problem that it is inconvenient to inject water due to equipment obstruction in the water injection area affecting the movement of the mobile vehicle body 1 is solved, so that the water injection situation can be flexibly changed according to the actual use situation. Under the action of the sleeve 503, the stability of the drainage elbow 506 can be increased, and the water level detection will not be affected by the shaking of the drainage elbow 506, further improving the use effect of the device. It is simple and convenient, meeting the actual use requirements, and avoiding the winding of the flexible hose 514. During the process of water being discharged through the drainage elbow 506, the drainage volume is detected in real time through the flow meter 507. Since the flow meter 507 is installed on the drainage elbow 506, the drainage volume can be accurately measured, avoiding the influence of the water remaining in the flexible hose 514 on the accuracy of the drainage volume. When the drainage elbow 506 corresponds to the water injection hole, pull out the bolt 509 from a set of lock holes 508, and at the same time stretch the spring 510. Then move the connecting plate 501, so that the connecting plate 501 moves on the surface of the mobile vehicle body 1 through the slide rail 502. Through the movement of the connecting plate 501, the drainage elbow 506 can be driven to move. Until the drainage elbow 506 moves into the water injection hole, at this time the spring 510 rebounds and drives the bolt 509 to insert into the lock hole 508 to complete the position locking of the connecting plate 501 and the drainage elbow 506. By moving the drainage elbow 506 into the water injection hole, it can effectively avoid the water splashing outside the water injection hole in a strong wind environment, and can also realize the detection of the water level, further improving the use effect of the device.
