[0002] A deep well pump is a water-lifting machine that works by submerging the motor and the water pump directly into the water. It is suitable for extracting groundwater from deep wells, and can also be used in water-lifting projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and water for people and livestock in plateaus and mountainous areas, and can also be used for water supply and drainage in cities, factories, railways, mines, and construction sites. Since the motor and the water pump body of a deep well pump are directly submerged in the water, whether it is safe and reliable will directly affect the use and working efficiency of the deep well pump. Therefore, deep well pumps with high safety and reliability have become the first choice.

[0003] When using a deep well pump to extract groundwater from a deep well, the power supply cable of the deep well pump needs to be lowered into the well according to the depth of the well. Deep well pumps usually require three-phase electricity, which means that three power supply cables need to be lowered at the same time. The power supply cables commonly used for deep well pumps are usually φ 150 mm, and each meter weighs about 3 kg. Therefore, to lower a three-phase power supply deep well pump into a 200-meter deep well, it usually requires 6 operators to cooperate with each other to lay the power supply cable, and it takes 6 hours of uninterrupted work to successfully lower the power supply cable into the well. Therefore, the existing cable laying operation process has the following shortcomings: the laying operation is time-consuming and labor-intensive, the construction efficiency is low, and the laying operation intensity is high.

[0018] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached manual. Figure 1 The positional relationships such as front, back, top, bottom, left, and right are described according to the layout directions of the drawings in the specification.

[0019] The present invention is further described below in conjunction with the embodiments and drawings:

[0020] Embodiment 1: As attached Figure 1 , 2 As shown, the deep well pump line-releasing device includes a triangular bracket and a fixed shaft 1, the fixed shaft 1 is fixedly installed on the top of the triangular bracket, at least one sleeve 2 is sleeved on the outside of the fixed shaft 1, a left vertical plate 3 and a right vertical plate 4 are fixedly installed on the lower left and right ends of each sleeve 2, a line-releasing roller 5 is provided between the front lower end of the left vertical plate 3 and the front lower end of the right vertical plate 4, and a limiting clamp is provided between the middle rear side of the left vertical plate 3 and the middle rear side of the right vertical plate 4 corresponding to the position above the line-releasing roller 5.

[0021] During use, as needed, three deep well pump pay-off devices with a single sleeve 2 can be used to lay power cables, or a deep well pump pay-off device with three sleeves 2 can be used to lay power cables. In this embodiment, in order to ensure the synchronization of laying power cables, a deep well pump pay-off device with three sleeves 2 is used, and the three sleeves 2 are arranged on the fixed shaft 1 at intervals. In order to facilitate the placement of the power cable in the wire groove on the upper side of the pay-off roller 5, the pay-off roller 5 and the left vertical plate 3 and the right vertical plate 4 can be fixed together in a detachable connection manner. The pay-off roller 5 can use a pay-off wheel or pay-off disk with a wire groove in the prior art. In this embodiment, a dumbbell-shaped pay-off roller shaft is used, which may include a dumbbell-shaped wire wheel and a spool. The spool is used to connect with the left vertical plate 3 and the right vertical plate 4. A dumbbell-shaped wire wheel is sleeved on the outside of the spool. The wire groove outside the dumbbell-shaped wire wheel is an arc-shaped wire groove. The dumbbell-shaped wire wheel can rotate around the spool axis. In order to facilitate the dumbbell-shaped wire wheel to rotate more smoothly, a rolling bearing or a sleeve or a self-lubricating bearing can be provided between the dumbbell-shaped wire wheel and the spool. The limit clamp can be realized using a U-shaped clamp in the prior art.

[0022] Before use, under the action of gravity, the pay-off roller 5, the left vertical plate 3 and the right vertical plate 4 can be naturally suspended above the ground; after the power supply cable is passed through the corresponding limit clamps and the wire grooves above the pay-off roller 5 in turn, during the laying of the three-phase power supply cable into the well, the power supply cable can automatically adjust the angle between the pay-off roller 5 and the wellhead axis, thereby making the laying of the power supply cable more time-saving and labor-saving, and effectively improving the laying efficiency of the power supply cable; during the laying of the power supply cable, the limit clamp can effectively prevent the power supply cable from slipping out of the wire groove on the pay-off roller 5, and can also hold the power supply cable together with the pay-off roller 5, so that the power supply cable laying process does not require manual lifting of the power supply cable, effectively reducing the working intensity of the deep well pump power supply cable laying operation, and greatly reducing the labor cost.

[0023] The above-mentioned deep well pump laying-out device can be further optimized and / or improved according to actual needs:

[0024] Embodiment 2: As attached Figure 1 , 2 As shown, the limiting clamp includes a fixed card 6, an active card 7, a first pin 8 and a connecting piece. The front side of the left end of the fixed card 6 is fixedly installed together with the rear side of the middle part of the left vertical plate 3, and the front side of the right end of the fixed card 6 is fixedly installed together with the rear side of the middle part of the right vertical plate 4. The right part of the fixed card 6 and the right part of the active card 7 are hinged together through the first pin 8. The middle part of the fixed card 6 is provided with an upper arc-shaped notch 9 which opens downward and passes through front and back. The active card 7 corresponding to the position of the upper arc-shaped notch 9 is provided with a lower arc-shaped notch 10 which opens upward and passes through front and back. The right part of the fixed card 6 and the right part of the active card 7 are detachably connected together through a connecting piece.

[0025] During use, after disassembling the right part of the fixed card 6 and the movable card 7, the power supply cable can be placed in the limiting hole formed by the upper arc notch 9 and the lower arc notch 10, which can effectively prevent the power supply cable from slipping out of the wire groove on the pay-off roller 5 and can also better support the power supply cable during the laying process.

[0026] According to the requirements, the connecting piece can realize the detachable connection and locking between the fixed card 6 and the right part of the movable card 7 by means of a latch-type clamp or a bolt or a switch-type electromagnet or a cam locking mechanism in the prior art.

[0027] Embodiment 3: As attached Figure 1 , 2 As shown, the connecting piece is a connecting bolt 11, an upper clamping platform 12 is fixedly installed on the outer side of the left end of the fixed clamp 6, a lower clamping platform 13 is fixedly installed on the outer side of the left end of the movable clamp 7 corresponding to the position of the upper clamping platform 12, a connecting screw hole that passes through from top to bottom is provided in the middle of the lower clamping platform 13, a connecting hole that passes through from top to bottom is provided on the upper clamping platform 12 corresponding to the position of the connecting screw hole, and a connecting bolt 11 with the lower part located in the connecting screw hole is provided in the connecting hole.

[0028] By such arrangement, the connecting bolt 11 can quickly connect and lock the fixed card 6 and the right part of the movable card 7 together. By loosening the connecting bolt 11, the connection state between the right part of the fixed card 6 and the right part of the movable card 7 can be quickly released.

[0029] According to the requirements, in order to facilitate manual operation, the connecting bolt 11 can be realized by a butterfly bolt or a hand-tightened bolt in the prior art.

[0030] Embodiment 4: As attached Figure 1 , 2 As shown, the triangular bracket includes a left bracket and a right bracket 14 spaced apart from each other, the left end of the fixed shaft 1 is fixedly installed with the right side of the upper end of the left bracket, and the right end of the fixed shaft 1 is fixedly installed with the corresponding position on the left side of the upper end of the right bracket 14;

[0031] The left bracket includes a left front support 15, a left rear support 16 and a left support part. The left rear support 16 is hingedly connected to the rear side of the middle of the left front support 15. The left support part is detachably installed between the left side of the lower part of the left rear support 16 and the left side of the lower part of the left front support 15. The left support part includes a left cross brace 18, a left connecting nail 19 and a left tightening nail 20. A left guide chute 21 opening to the left is provided on the left side from the upper part to the lower part of the left rear support 16. The left connecting nail 19 is slidably installed on the inner side of the lower part of the left guide chute 21. The left cross brace 18 is rotatably installed on the outer side of the left part of the left connecting nail 19. The front end of the left cross brace 18 is fixedly installed with the left left side of the lower part of the left front support 15 by the left tightening nail 20.

[0032] The right bracket 14 has the same structure as the left bracket and is symmetrically distributed.

[0033] During use, loosen the left tightening nail 20 and push the left rear support 16 forward, so that the left cross brace 18 rotates around the left tightening nail 20. At this time, the rear end of the left cross brace 18 can move upward along the left guide slot 21, thereby folding the left rear support 16 and the left front support 15 together. Similarly, the same method can be used to fold the right bracket 14 to facilitate the folding, storage and transportation of the device.

[0034] After the device is carried to the wellhead, the left rear support 16 is pulled backward to quickly unfold the left support. After the left front support 15, the left rear support 16 and the left cross brace 18 form a triangular support structure, the left fixing nail 20 is tightened to fix the front end of the left cross brace 18 and the left front support 15 together to form a stable triangular structure. Similarly, the right support 14 can be unfolded, so that the device can be reliably and stably supported on the ground. In addition, the left and right supports 14 in the shape of an I can better guide the power supply cable into the well.

[0035] According to the requirements, the left bracket and the right bracket 14 in this embodiment can be realized by a square tube or a rectangular tube in the prior art, wherein the cross brace can also be realized by angle iron or steel plate. To prevent the left bracket and the right bracket 14 from being corroded by rain or dew, the upper and lower ends of the triangular bracket can be fixedly installed with a blocking piece 26. The rear side of the middle part of the left front support 15 and the left rear support 16 can be hinged together by a hinge 17. The left connecting nail 19 can be realized by a T-shaped screw in the prior art.

[0036] Embodiment 5: As attached Figure 1 , 2 As shown, the triangular bracket further includes a front stabilizing support rod 22 and a rear stabilizing support rod 23, which are fixedly installed at a front-to-back interval between the lower end of the left bracket and the lower end of the right bracket 14.

[0037] By configuring in this way, the weight of the bottom end of the tripod bracket can be increased, thereby improving the stability of the tripod bracket.

[0038] Embodiment 6: As attached Figure 1 , 2 As shown, a guide device capable of guiding the moving direction of the power supply cable is provided in the middle part of the right side of the tripod bracket, and the guide device includes a guide roller 24 and a hook 25. Two hooks 25 are fixedly installed at intervals in front and back in the middle part of the right side of the tripod bracket, and the left end of the guide roller 24 is located in the hook 25 on the left side, and the right end of the guide roller 24 is located in the hook 25 on the right side.

[0039] During use, the front side of the guide roller 24 can support and hold the power cable, so that the power cable can slide into the well more smoothly. When the power cable moves into the well, the guide roller 24 can be driven to rotate under the action of friction, so that the guide roller 24 rotates in the hook 25, thereby reducing the friction between the guide roller 24 and the power cable.

[0040] Embodiment 7: A rolling bearing is provided between each sleeve 2 and the fixed shaft 1 .

[0041] By configuring in this way, the sleeve 2 and the fixed shaft 1 can rotate more smoothly.

[0042] The above technical features constitute the embodiments of the present utility model, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
